Elimination Method:

The equations are

              Equation (1)

                 Equation (2)

Multiply the second equation by 3.

Since the coefficients of the y-terms 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 the corresponding columns.

Divide each side by 10.

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

              (Equation 2)

Add to each side.

Subtract 7 from each side.

Multiply each side by 2.

The solution is .
