Question 982797
Hi there,
Make 'x' the number
add 3 to the number, divide the result by 5
(x + 3)/5
= the same answer as I take away 5 from it
(x + 3)/5 = x - 5
Common denominator 5
x + 3 = 5(x - 5)
x + 3 = 5x - 25
Collect like terms
x - 5x = -25 - 3
-4x = -28
  x = 7
The number is 7
Hope this helps:-)
