What is the solution to this equation : 1/21x = 1/7

x = 3

x = 14

x = 28

x = 147

Answer: x=3

Step 1: multiply both sides of the equation by 21

21 * 1/21 x = 21 * 1/7

Step 2: Reduce the number with the greatest common factor 21.

x = 21 * 1/7

Step 3: Reduce the number with the greatest common factor 7.

x=3
