Faruq subtracted 5 from a number and then divided by 4. Next, he subtracted 4 from the original number and then divided by 5. He got the same final answer both times. What was the original number?
(x-5)/4 = (x-4)/5 given
5 ( x-5) = 4 ( x-4) solve for the number 'x'
OOH, OOH, MR. PAVLOV I CAN DO IT!
5x-25=4x-16
5x-25+25=4x+9
5x=4x+9
x=9
