    Simple. Just get x to stand alone.

    20x=5-3 Subtract 3 from both sides.
    20x=2
    x=2/20 Divide 20 on both sides.
    x=1/10 Simplify.

    20x+3=5
    Subtract 3 from both sides of the equation.

    20x = 2
    Divide both sides by 20

    x = 2/20
    x = 1/10
    ________________________________

    4-x=9

    Add x to both sides.
    5 = 9 + x

    Subtract 9 from both sides.
    4-9 = x
    -5 = x
