Question

Y=x+8 and 4x-2y=-6 need to show work

Answer 1

Answer: x = -1, y = 7

Explanation:

4 *(y - x = 8) --> 4y - 4x = 32

-2y + 4x = -6 --> -2y + 4x = -6

if we subtract the derived equations from each other we find a new equation which is: 4y + 2y = 42

From this, we find that y = 7

and when we put the y-value in one of the original equations we find that x is -1:

7 - x = 8

x = -1
