The equations are

              Equation (1)

                   Equation (2)

Multiply the second equation by 5

Now the equation is

             Equation (2)

Since the coefficients of the y-terms, -20 and +20, are additive inverses,

you can eliminate these terms by adding the equations.

Add the equations to eliminate variable y.

(write the equations in column form and add)

                      (Divide each side by 26)

                                (Cancel common terms)

                                        (Divide: )

Now Substitute 8 for x in either equation to find the value of y.

                 (Equation 2)

             (Replace y by 16)

                 (Multiply: )

  (Subtract 24 from each side)

                (Apply additive inverse property: )

                         (Subtract: )

                    (Divide each side by 4)

                         (Cancel common terms)

                              (Divide: )

The solution is (x, y) = (24, 3)

The solution is (x, y) = (24, 3).
