The equations are

                      Equation (1)

                       Equation (2)

Multiply the second equation by 4

Now the equation is

                     Equation (2)

Since the coefficients of the x-terms, +4 and +4, are additive inverses,

you can eliminate these terms by adding the equations.

Subtract the equations to eliminate variable y.

  (write the equations in column form and subtract)

           (Divide each side by 11)

                    (Cancel common terms)

                         (Divide: )

Now Substitute either equation to find the value of x.

            (Equation 2)

                     (Replace y by )

        (Subtract 8 from each side)

                     (Apply additive inverse property: )

                              (Subtract: )

The solution is (x, y) = (5, )

The solution is (x, y) = (5, ).
