how do you solve for x and y?

3x-2(y+2)=-6
4(x+1)-y=7

  • geometry - ,

    3x-2y-4=-6
    3x-2y=-2*
    4x+4-y=7
    4x-y=3*
    So your 2 new equations are
    3x-2y=-2
    4x-y=3
    Multiply the bottom equation by -2 to cancel the y's gives us
    -8x+2y=-6
    3x-2y=-2
    -5x=-4
    x=4/5
    Plug the x value into either of your "2 new equations above" to figure out y.
