When you subtract 5 from a number x and divided the answer by 7 the result is 23 less than x Find x?

So you have:
(x - 5)/7 = x - 23 (multiply both sides by 7)
x - 5 = 7x - 161 (subtract x and add 161 to both sides)
156 = 6x (divide both sides by 6)
x = 26
Mistakes (below):
5 - x = subtract x from 5, but we want to subtract 5 from x.
the answer/7 = 23 less than x = subtract 23 from x = x - 23
if you tried to ask 5-x=__/7= 23 the answer is 166
5-x=__/7=23
first you would multiply 7 x 23 which is 161
5-x=161
second you would add 5 on both sides since you are subtracting in the problem
5+5-x=161+5
third you add 161 and 5 together and you would get 166
so x=166
