Question 199355
I am thinking of a whole number. If I divide it by 13, then multiply the answer
 by 12, then subtract 20, and then add 89, I end up with 93.
 What was my original number?
:
x = "a number"
:
({{{x/13}}} * 12) - 20 + 89 = 93
:
({{{x/13}}} * 12) + 69 = 93
:
{{{(12x)/13}}} = 93 - 69
:
{{{(12x)/13}}} =  24
:
Multiply both sides by 13
12x = 24 * 13
:
12x = 312
x = {{{312/12}}}
x = 26 is the number
:
:
Check solution in original statement
({{{26/13}}} * 12) - 20 + 89 = 93
(2*12) - 20 + 89 = 93
