Unveiling Infinite Solutions Mastering The Art Of Solving Systems Of Equations

Hey guys! Today, we're diving deep into the fascinating world of solving systems of equations, and we're going to tackle a problem that might seem a bit tricky at first glance. We'll be looking at a system that has infinitely many solutions, which is a super cool concept in mathematics. So, buckle up, grab your pencils, and let's get started!

The System of Equations

Let's take a look at the system of equations we're going to solve:

10x + y = 22
2x + y = -2

This looks like a pretty standard system, right? We've got two equations and two variables (x and y), so our goal is to find the values of x and y that satisfy both equations simultaneously. There are several methods we could use to solve this, such as substitution or elimination. But as we'll see, this particular system has a twist!

Exploring the Substitution Method

One common approach to solving systems of equations is the substitution method. In this method, we solve one equation for one variable and then substitute that expression into the other equation. Let's try this with our system. From the first equation, we can isolate y:

y = 22 - 10x

Now, we can substitute this expression for y into the second equation:

2x + (22 - 10x) = -2

Okay, let's simplify this equation and see what we get. Combining like terms, we have:

-8x + 22 = -2

Subtracting 22 from both sides:

-8x = -24

Dividing both sides by -8:

x = 3

Great! We've found a value for x. Now, we can substitute this value back into either of the original equations to find y. Let's use the first equation:

10(3) + y = 22
30 + y = 22
y = -8

So, it looks like we have a solution: x = 3 and y = -8. Let's check if this solution works in both equations:

Equation 1: 10(3) + (-8) = 30 - 8 = 22 (Correct!) Equation 2: 2(3) + (-8) = 6 - 8 = -2 (Correct!)

So far, so good. We've found one solution. But is it the only solution? That's the question we need to explore further.

Unveiling the Infinite Solutions Mystery

Now, let's try a different approach. Instead of solving for a specific value, let's substitute the expression for y (y = 22 - 10x) back into the first equation itself. This might seem a bit strange, but bear with me:

10x + (22 - 10x) = 22

Simplifying this, we get:

10x + 22 - 10x = 22

Notice what happens next:

22 = 22

Whoa! The x terms canceled out completely, and we're left with a statement that is always true. This is a huge clue! It means that our initial assumption that we'd find a single, unique solution might be incorrect. When we arrive at an identity (a statement that is always true), it indicates that we're dealing with a system that has infinitely many solutions.

What Does Infinitely Many Solutions Really Mean?

So, what does it mean for a system of equations to have infinitely many solutions? Geometrically, it means that the two equations represent the same line. In other words, the equations are just different ways of writing the same relationship between x and y. Any point that lies on this line will satisfy both equations.

Think of it this way: if you graph both equations, you'll find that they perfectly overlap. There isn't a single intersection point; instead, every point on the line is a solution.

To illustrate this, let's rewrite the second equation in slope-intercept form (y = mx + b):

2x + y = -2
y = -2x - 2

Now, let's multiply this equation by -5:

-5y = 10x + 10

Rearranging the first original equation gives us:

y = 22 - 10x

If we rearrange the second original equation gives us:

y = -2 - 2x

You can see that these lines, while looking different, are actually representing similar relationships. This is why we get infinitely many solutions.

Expressing Infinite Solutions

When a system has infinitely many solutions, we don't list out every single solution (because, well, there are infinitely many!). Instead, we express the solution in a general form. Since the equations represent the same line, we can simply use either equation to describe the relationship between x and y. For example, we can say that the solutions are all the points (x, y) that satisfy the equation:

y = 22 - 10x

This tells us that for any value of x we choose, we can find a corresponding value of y that makes both equations true. This is a concise way to represent the infinite solutions of the system.

Discussion and Category

This type of problem falls squarely into the realm of mathematics, specifically the branch of algebra that deals with systems of equations. The concept of infinitely many solutions is a crucial one in linear algebra and has applications in various fields, including computer graphics, economics, and engineering.

Repairing the Input Keyword

The original phrasing of the problem could be improved to be more precise. Instead of just saying "Solve the system below," we could ask:

"Determine the solution set for the following system of equations. If there are infinitely many solutions, express the solution in terms of a parameter."

This revised question is clearer and guides the solver towards the expected type of answer, especially when dealing with infinite solutions.
