Question 1016447: Harry is X years old. Three years ago Jenny was twice as old. In three years time Ahmed will be 5 times as old as Jenny. Write an expression for Ahmed's age Found 2 solutions by fractalier, Alan3354:Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! Harry is x now.
Jenny is j now.
Ahmed is a now.
j-3 = 2(x-3) which means j = 2x - 6 + 3 = 2x - 3
In three years,
a + 3 = 5(j + 3)
now solve for a substituting in we get
a = 5(2x - 3 + 3) - 3 = 10x - 3
