Question 149969
Seven years ago, Yves was six times as old as Eric. in one year, he will only be twice as old as Eric. What are their present ages?
---------------------
Let Yves be y yrs. old now.
Let Eric be e yrs. old now.
------------------------------
EQUATIONS:
(y-7) = 6(e-7)
y+1 = 2(e+1)
------------------
Rearrange equations:
y = 6e -35
y = 2e + 1
---------------
6e -35 = 2e+1
4e = 36
e = 9 yrs old (Eric's age now)
---------
y = 2*9+1 = 19 (Yves's age now)
