The system of equations are and .

Solve the system of equations with elimination method.

Step 1:

Multiply each equation with a suitable multiplier. \ \

                  (Second equation)

        (Multiply each side by )

               (Multiply)

Step 2:

Add the equations to eliminate the one varible.

                 (Divide each side by )

                              (Cancel common terms)

Step 3:

Substitute into any original equation to find value. 

                 (Second equation)

                (Substitute )

                     (Multiply)

(Subtract from each side)

                          (Apply additive inverse property: )

                     (Divide each side by )

                               (Cancel common terms)

Therefore, the solution of the system is .

The solution of the system is .
