Question 252633: Gideon is 30 years younger than his father, His mother is three times as old as her son. Find Gideon's age if his father is two years older than his mother. Answer by drk(1908) (Show Source):
You can put this solution on YOUR website! Let G = Gideon M = mother, and F = father.
(i) G = F - 30.
(ii) M = 3G
(iii)F = M + 2.
Substitute (iii) into (i) to get
(iv) G = M + 2 - 30
(ii) M = 3G
Substitute (ii) into (iv) to get
(v) G = 3G + 2 - 30.
Solve for G.
-2G = -28
G = 14.
M = 42.
F = 44.
