3x-7=14
+7 +7
3x=21
X=7
I think that’s the answer
Let 'n' represent the unknown number being multiplied. 

3n - 7 = 14

Add 7 to both the 7 and the 14.

3n = 21

Divide both sides by 3.

n = 7

Check your work by substituting 7 into the 'n' place in order to get a true statement. 

3(7) - 7 = 14
21 - 7 = 14
14 = 14
