Five times a number is divided by 7 more than that number minus 4. If the result is 18, then what was the original number.
let the number be x
(Five times a number)is divided by (7 more than that number minus 4) = 18
5x is divided by ( 7+x-4 ) =18
5x is divided by x+3 =18
\(\frac{5x}{x+3}=18\\ 5x=18x+54\\ -13x=54\)
you can finish it.
-------------
It is possible that the question intended
\(\frac{5x}{x+7}-4=18\)
But I think the first interpretaion is more reasonable.
