h = husband's age
w = wife's age
s = son' age
write an equation for each statement
:
husband is 7 years older than his wife,
h = w + 7
:
if his wife is 3 times and 2 years old as her son
w = 3s + 2
:
how old is the husband and wife if the son is 12 years?
replace s with 12 in the above equation
w = 3(12) + 2
w = 38 yrs is the wife
then find husband's age using the 1st equation
