Please help me! Im lost on where to start.

1.)Solve: 3/2z+4z=1
2.)Solve the following equation: x-2/x+2=x+2/x+4

    The way you typed it ....

    1.
    multiply every term by 2 ...
    3z + 12z = 3
    15z = 3
    z = 3/15 = 1/5

    2. each term by x

    2 + 2x = x^2 + 2 + 4x
    x^2 + 2x = 0
    x(x+2) = 0

    x = 0 or x = -2

    I have a feeling you meant to have brackets in those equations.
