The equations are $\"\"$ $\"\"$

$\"\"$ Equation (1)

$\"\"$ Equation (2)

Multiply the first equation by 4.

$\"\"$

$\"\"$ Equation (3)

$\"\"$

Since the coefficients of the y-terms are additive inverses, y-terms can be eliminated by adding the equations 2 and 3.

Write the equations in column form and add the corresponding columns.

$\"\"$

$\"\"$ (Divide each side by –11)

$\"\"$ (Divide: $\"\"$ )

$\"\"$

Now substitute 2 for x in either equation to find the value of y.

$\"\"$ (Equation 2)

$\"\"$ (Replace x by –2)

$\"\"$ (Multiply: $\"\"$ )

$\"\"$ (Add 6 to each side)

$\"\"$ (Add: $\"\"$ )

$\"\"$ (Divide each side by 4)

$\"\"$ (Divide: $\"\"$ )

The solution is $\"\"$
