[quote=Anonymous]Ok, I think I got it. (no guarantees) Sara = x Sondra = 2x Sol = y Sal = y + 3 Sigmund = 6y Sherry = 6y + 12 or 2 [(y+3) + x] total = 144 First, you need to figure out what X is in terms of y. So you use Sherry to solve for X 6y + 12 = 2y + 6 + 2x 4y + 6 =2x 2y + 3 =x So now you add up all the ages, replacing 2y + 3 for x. (2y +3) + 2(2y +3) + y + y+3 + 6y + 6y + 12 = 144 2y + 3 + 4y + 6 +2y +3 +12y + 12 = 144 20y + 24 = 144 20y = 120 y = 6 Sol = y = 6 Sal = y+3 = 9 Sigmund = 6y = 36 Sherry = 6y+12 = 48 Sara = (2y + 3) = 15 Sondra = 2(2y+3) = 30 total = 144 [/quote]
