Answer:

5y + 2y - 4x + 4x = -7 +14

7y = 7

y = 1

2(1) + 4x = 14

4x = 12

x = 3

Step-by-step explanation:

Using the process of elimination

Add both equations. The 4x will be eliminated since one is positive and one is negative. The equation is left with only the y variable and the constant.

When y is found, input it into the second equation to find x.
