Math Problem Statement

3x - 2y = 5 - 6x + 4y = - 10

Solution

It looks like you're trying to solve the following system of linear equations:

  1. 3x2y=53x - 2y = 5
  2. 6x+4y=10-6x + 4y = -10

Let's solve this system step by step using either substitution or elimination. I'll proceed with the elimination method for clarity.

Step 1: Multiply the first equation to eliminate the variable yy

To eliminate yy, notice that the second equation has a term 4y4y, which is double the term 2y-2y in the first equation. Let's multiply the first equation by 2 to align the coefficients of yy:

2(3x2y)=2(5)2(3x - 2y) = 2(5) This simplifies to: 6x4y=106x - 4y = 10

Now we have:

  1. 6x4y=106x - 4y = 10
  2. 6x+4y=10-6x + 4y = -10

Step 2: Add the two equations together

Now, we add the two equations together to eliminate yy:

(6x4y)+(6x+4y)=10+(10)(6x - 4y) + (-6x + 4y) = 10 + (-10)

This simplifies to:

0=00 = 0

Step 3: Interpret the result

The equation 0=00 = 0 indicates that the two equations are not independent, meaning they represent the same line. Therefore, the system has infinitely many solutions.

Conclusion

The system of equations represents the same line, so there are infinitely many solutions. Any pair (x,y)(x, y) that satisfies one equation will also satisfy the other.
