    Answer:

    one solution:  x = -3,  y = 26

    Step-by-step explanation:

    3x + y = 17

    x + 2y = 49

    If you multiply the first equation by -2 and then add you will eliminate the ‘y’ term

    -2(3x + y) = -2(17)

      -6x – 2y = -34

    +    x + 2y = 49

       -5x = 15

         x = -3

    -3 + 2y = 49

    2y = 52

    y = 26
