  • Answer:

    x = 4, y = -2.

    Step-by-step explanation:

    -3y + 5x = 26

    -2y - 5x = -16

    Adding these will eliminate x:

    -5y  + 0 = 10

    y = 10/-5 = -2.

    Substitute for y in the first equation:

    -3(-2) + 5x = 26

    5x = 26 - 6

    5x = 30

    x = 4.

    Check to see if these roots are correct in the second equation:

    Left side  -2(-2) - 5(4)  = 4 - 20 = -16,  so they are correct.
