Solve the Equation

Question

(n-3) = 7

   3

 

Show work.

 

Multiple Choice:

A) 24

B) 18

C) 30

D) 12

Answer 1

I assume you meant

 

(n - 3) / 3 = 7

 

Multiply both sides by 3 and get

 

n - 3 = 3*7 = 21

 

Add 3 to both sides and get

 

n = 21 + 3 = 24

 

The correct answer is (A).
