Boys and money

270 USD boys divided so that Peter got three times more than Paul and Ivan has 120 USD more than Paul. How much each received?

Correct answer:

a =  90
b =  30
c =  150

Step-by-step explanation:


a+b+c=270
a=3b
c= 120+b

a+b+c=270
a=3•b
c= 120+b

a+b+c = 270
a-3b = 0
b-c = -120

a = 90
b = 30
c = 150
