<h3><u>The value of y is -7.</u></h3><h3><u>The value of x is 8.</u></h3>

First we need to rearrange these equations so they line up properly.

6x - 2y = 62

-x + 2y = -22

Add equations together.

5x = 40

Divide both sides by 5.

x = 8

We can plug this value in to find the value of y.

6(8) - 2y = 62

48 - 2y = 62

Subtract 48 from both sides.

-2y = 14

Divide both sides by -2.

y = -7
