  1. You want everything with x in it on the left and everything without x on the right
    So
    add -18 to both sides
    then divide both sides by 4 to get 1x instead of 4x

  2. 4x+18=22

    First, subtract the known number on the left side from each side of the equation.

    4x + 18 - 18 = 22 - 18
    4x = 4

    Divide both sides of the equation by 4.

    x = 1

    Let's prove it.
    4 * 1 + 18 = 22

    Yep. It's right!
