How do you solve system of equation problem. example
x+3y=32
-3x+2y+3
and
x+y=6
x-y=-9

  • MATH 101 - ,

    x + 3y = 32
    -3x + 2y = 3

    Add 3x1st to 2nd to produce

    11y = 99
    y = 9
    so,
    x = 5
    ___________

    x + y = 6
    x - y = -9

    add the two equations to get

    2x = -3
    x = -3/2
    so,
    y = 15/2
