[tex] \frac{3x}{3} [/tex][tex] \frac{3x}{3} [/tex][tex] \frac{3x}{3} [/tex]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

Answer:

                        x = 14/3
