The equations are

                        Equation (1)

                      Equation (2)

Since the coefficients of the x-terms additive inverses, you can eliminate

these terms by adding the equations. Add the equations to eliminate variable x.

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

                  (Multiply each side by negative one)

                                      (Product of two same signs is psoitive)

\

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

                      (Equation 2)

                  (Replace y by 2)

                        (Multiply: )

            (Add 6 to each side)

                        (Additive inverse property: ) \ \

                                (Add: )

                           (Divide each side by 4)

                                  (Cancel common terms)

The solution is .
