Answer:
x = -2
y = 4
Step-by-step explanation:
Since the two equations can cancel out the "y" when you add them, you don't need to modify any of the equations.
Just simply, add the two equations together using like terms.
-5x + (-2x) = -7x
-6y + 6y = 0
-14 + 28 = 14
Now, you have the following equation:
-7x = 14
x = -2
Plug the number back into one of the equations as the "x" to find the y.
-2(-2) +6y = 28
y = 4
