Question 904532: Rob is 5 years older than John. Mark is twice as old a John. The total of their ages is 65 . Write an equation and solve to find the ages of John, Rob, and Mark. Answer by ewatrrr(24785) (Show Source):
You can put this solution on YOUR website! x John's age
Rob + Mark + John = 65
(x+5) + 2x + x = 65
4x = 60
x = 15, John's age. Rob is 20 and mark is 30
And..checking
sum = 65
