5x + 2y = 16 ⇒ 5x + 2y = 16
  x + 3y = 12 ⇒ <u>5x + 15y = 180</u>
                                <u>-13y</u> = <u>-164</u>
                                 -13      -13
                                     y = 12 8/13
               5x + 2(12 8/13) = 16
                   5x + 25 3/13 = 16
                   <u>       -25 3/13   -25 3/13</u>
                                   <u>5x</u> = <u>-9 3/13</u>
