Multiply each equation by a number that produces opposite coefficients for x and y.

4x+5y=7 x= ?

3x-2y= -12 x=?

Possible answers for both.
-5,-4,-3,-2,-1,1,2,3,4,5

Answer 1

-1

Explanation:

4x+5y=7

3x-2y= -12

To get the opposite coefficient, we multiply by -1

-1(4x+5y=7 )

-4x-5y = -7

-1*(3x-2y= -12)

-3x +2y = 12

Both equations now have the opposite coefficients on both x and y.
