Question

Dorothy is 14 years younger then Rita. Ten years ago, rita was 3 times as old as dorothy was then. how old is each now?
step by step plz :)

Answer 1

I think I've got the answer. See what you think.

We have that D (Dorothy) = R (Rita) - 14
and we are told that 10 years ago Rita's age was equal to 3 times Dorothy's, so
(R-10) = 3(D-10)
R-10 = 3D - 30
R = 3D - 20

Now we can find R because we know that D = R-14 and by substituting this into the equation we have only one variable.

R = 3(R-14) - 20
R = 3R - 42 - 20
-2R = -62
therefore R = 31

You can use this to find D and then verify that 10 years ago R was equal to 3D
