If you subtract 9.4 from one-third of a number, the result is 8.7 . what is the number?

x/3 - 9.4 = 8.7.
x/3 = 8.7 + 9.4.
x = 3(8.7 + 9.4).
x = 3(18.1).
x = 54.3.

9.4 + 8.7 = 18.1 x 3 = 54.3
I think this ? needs rounding up.
9.4 + 8.7 =(18.1) 18 x 3 = 54
Hey if this is your home work ignore my answer as this is purely a guess.

taking the number as x
therefore, (x/3) - 9.4 = 8.7
=> (x - 9.4*3)/3 = 8.7
=> x - 28.2 = 8.7*3
=> x -28.2 = 26.2
=> x = 28.2 + 26.2
=> x = 54.3
so the required number is 54.3

Let x = a number
Equation
1/3x - 9.4 = 8.7
1/3x - 9.4 + 9.4 = 8.7 + 9.4
1/3x = 18.10
Multiply both sides by 3
3 (1/3x) = 3(18.10)
x = 54.3 ====> the number
To check:
1/3x - 9.4 = 8.7
1/3(54.3) - 9.4 = 8.7
18.1 - 9.4 = 8.7
8.7 = 8.7
HOPE YOU UNDERSTAND !!!!

let the number be x
(1/3)x-9.4=8.7
(1/3)x=8.7+9.4
x=18.1*3
x=54.3

1/3x - 9.4 = 8.7
1/3x - 9.4 + 9.4 = 8.7 + 9.4
1/3x = 18.1
3(1/3x) = 3(18.1)
x = 54.3
The number is 54.3
