Question

When six times a number is decreased by 9, the result is 3. What is the number?

Answer 1

Lets say the number = x

Six times a number is decreased by 9, the result is 3
6 times x is decreased by 9, the result is 3  
(decreased means to subtract and results means equals)

6x - 9 = 3         (add 9 to each side)
     +9    +9
6x = 3 + 9
6x = 12            (divide each side by 6)
6x/6 = 12/6
x = 2


The number is 2
