Elimination Method:

The system of 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.

Apply division property of equality: Divide each side by 8.

        ()

                    (Cancel common terms).

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

     (Equation 1).

        (Multiply: )

Apply subtraction property of equality: Subtract 32 from each side.

Rearrange the terms using commutative property of addition: .

\ \ (Apply additive inverse property: )

       (Apply additive identity property: )

             (Sbtract: )

        (Divide each side by negative 3)

                      (Cancel common terms)

The system of solution is .
