Question

Solve the system of equations.

3x+5y=9
3x+2y=3

1 Answer

  • eliminate
    multiply 2nd equtaon by -1 and add to first

    3x+5y=9
    -3x-2y=-3 +
    0x+3y=6

    3y=6
    divide by 3
    y=2

    sub back

    3x+2y=3
    3x+2(2)=3
    3x+4=3
    minus 4 both sides
    3x=-1
    divide by 3
    x=-1/3

    (x,y)
    (-1/3,2)
