    x+1 = - 1/2x+4

    subtract x from both sides

    1=-1 1/2x + 4

    subtract 4 from each side

    -3 = - 1 1/2x

    divide both sides by - 1 1/2

    x = 2

    check the answer:

    2+1 = 3

    -1/2 (2) + 4 = 3

    so X = 2

    Y=x+1

    y=-1/2x+4

    y=y

    x+1=-1/2x+4

    1x+1/2x+1=4

    3/2x=4-1

    3/2x=3

    x=3 / (3/2)

    x=2
