Answer: x=40 y=56

Explanation:

Multiply the entire equation by the common denominator to get rid of the denominator.

then the equation becomes when multiply first by 4 and second equation by 20

4(-3x+2y=-2) mult 4

3(4x-5y=-120) mult 3 to get rid of the x term

-12x+8y=-32

12x-15y=-360 add 2 equations

-7y=-392

y=56

4x-5(56)=-120 find easiest equation to plug y to solve for x

4x=160

x=40
