Question

Six less than three fourths of a number is nine. What is the number? Show the equation.

Answer 1

let x be the unknown number.

`(3)/(4) x - 6 = 9 \\ (3)/(4) x(4) - 6(4) = 9(4) \\ 3x - 24 = 36 \\ 3x = 36 + 24 \\ 3x = 60 \\ (3x)/(3) = (60)/(3) \\ x = 20`

THE UNKNOWN NUMBER IS 20

Answer 2

x = -4

Explanation:

`6-(3)/(4) x=9`

`-(3)/(4)x=9-6`

`x=(3)/(-(3)/(4) ) =-(12)/(3)`

`x=-4`
