aaron is 15 cenimeters taller than peter and five times aarons height exceeds two times peters height by 525 centimeters what is arrons height and what is peter height

Dec 10th, 2014

Assume aaron-a and peter-p

p+15=a

5a=2p+525

Solve simultaneously or substitute, I'll substitute

5(p+15)=2p+525

5p +75=2p+525

3p=450

p=150

Peter's height is 150 cm and Aaron's height is 165 :)
