Question

Nathan wants you to solve this puzzle i em thinting of a number. if you divide my number by 3 and add -3 you will get 4

Answer 1

n = 21

Your equation would be:

n/3 - 3 = 4

Add three to both sides because whatever you do on one side you have to do for the other side

n/3 = 7

Multiply both side by 3 to get rid of the fraction

n = 21
