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
