Question

Solve this system of linear equations. Separate

the x- and y-values with a comma.
-5x + 3y = 13
7x + 2y = -12

Answer 1

x = -2, y = 1

Explanation:

So you can solve this equation using subtraction.

Multiply the first equation by 2:

-10x + 6y = 26

Multiply the second equation by 3:

21x + 6y = -36

Subtract the two equations:

-31x = 62

x = -2

y = 1
