if the quotient of three times a number and four is decreased by three, the result is nine. whats the number

Question

question is above

Answer 1

Trevor,

 

number = x

 

(3x÷ 4) - 3 = 9

 

Use a common denominator 4: 3x - 12 = 36

3x = 48

x = 16

 

Does it fit the original equation?

[(3 x 16) ÷ 4] -3 = (48 ÷ 4) -3 = 12 - 3 = 9

 

Hope it helps
