Question 294333: Klye weighs twice as much as his younger sister Suzanne and 10 pounds less than his older sister margaret. All together they weigh 90 pounds. How much does Margaret Weigh? Answer by Deina(147) (Show Source):
You can put this solution on YOUR website! k = 2s
k = m - 10
m = 2s + 10
k + m + s = 90
/************************************/
k + s + 2s + 10 = 90
2s + s + 2s + 10 = 90
5s + 10 = 90
5s = 80
s = 16
k = 32
m = 42
and bob's your uncle!
