__Elimination Method:__

The equations are

Equation (1)

* * Equation (2)

Since the coefficients of *y*-terms are additive inverses, these terms can be elimanted by adding equations.* *Write the equations in column form and add the corresponding columns.

According to division property of equality: Divide each side by 2.

(Cancel common terms)

Now, find the *y* value by substituting in either equation.

(Equation 1)

According to subtraction property of equality: Subtract 2 from each side.

(Apply commutative property of addition: )

(Apply additive inverse property: )

(Apply additive identity property: )

(Subtract: )

The solution is .
