Question 992223
Assume the problem is
 Larry is 2x as old as Jane.
 Jane is 6years younger then Tony.
 and Tony is 12 years younger then Larry
 how old is each?
:
Write an equation for each statement
 Larry is 2x as old as Jane.
L = 2j
 Jane is 6years younger then Tony.
j = t - 6
 and Tony is 12 years younger then Larry
t = L - 12
Replace L with 2j
t = 2j - 12
Replace j with (t-6)
t = 2(t-6) - 12
t = 2t - 12 - 12
t - 2t = -24
-t = -24
t = 24 yrs is Tony's age
then
j = t - 6
j = 24 - 6
j = 18 yrs is Jane's ge
and
L = 2J
L = 2(18)
L = 36 yrs is Larry's age

You can check this for yourself in each statement.
