Answer:

y = -2; x = 6

Explanation:

First what you need to do is change the formatting of the second equation.

So it would be:

4x + 6y =12

4x - 2y = -20

Now that the equations are correct, just subtract the x values, y values, and whole numbers. You'll get 4y = -8 -> y = -2

Next, you'll plug in that y value into one of the equations to get the x value.

4x + 6(-2) = 12

4x + -12 = 12

4x = 24

x = 6

Therefore, the values are y = -2 and x = 6 :)
