This is the Mathematical translation of that verbal expression:

four plus three times a number is eighteen

4       +                    3x              =    18

Right now, what we are finding is x or the unknown number. To find x, subtract 4 to both sides, then divide both sides by 3.

4 + 3x = 18

4 + 3x - 4 = 18 - 4

3x = 14

3x/3 = 14 / 3

x = 14/3
