5x-2y=4
x+2y=8

  • algebra 1b -

    if you are trying to solve for the variables subtract 2y to the other side so you then have X=-2y +8 for the equation and put it in for x in the top equation
    5(-2y+8) -2y=4
    -10y+40-2y=4
    -12y=-36
    y=3
    so then put 3 in for the bottom equation
    x+2(3)=8
    x=2
