grandmother Alice says my daughter Mary is 26 years younger than me
and 34 years older than my granddaughter Lisa
if you add all of our ages together the total is 100
how old are Alice Mary and Lisa
:
Write three equations from the information given here
:
A = M + 26
L = M - 34
A + M + L = 100
:
In the last equation replace A with (M+26); replace L with (M-34), find M
(M+26) + M + (M-34) = 100
3M - 8 = 100
3M = 108
M = 108/3
M = 36 yrs is Mary's age
:
You should be able to find A and L, ensure they add up to 100
