    Add 2x to both sides and get 5x+18=3

    Then subtract 18 on both sides to get 5x=-15

    Finally Divide by 5 to get x=-3

    3x+18=3 - 2x

    +2x + 2x (add two to both sides)

    Then you have

    5x+18 = 3 (subtract 18 to both sides)

    -18 - 18

    5x+-15

    (divide both sides by 5)

    x = - 3
