The system of equations are and .

Solve the system of equations by elimination method.

Step 1:

Multiply each equation with a suitable multiplier.

                  (First equation)

        (Multiply each side by )

                (Multiply)

Step 2:

Subtract the equations to eliminate a variable.

             (Divide each side by )

                           (Cancel common terms)

Step 3:

Substitute into any original equation to find value.

                  (First equation)

            (Substitute )

                 (Multiply)

(Subtract from each side)

                            (Apply additive inverse property: )

                       (Divide each side by )

                              (Cancel common terms)
