John = J
Mary = M
J = 5 + M
(J+10)(M+10)= 39+10
M+5+10M+10=39+10
2M=24
M=12
J=17
12+17+10=39
Hey Joel thanx for helping me helpo myself :)
:
: : John = J
: : Mary = M
: : J = 5 + M
: : (J + M)+10 = 39 What is this???
: If John's age is J now, how old will he be 10 years from now?
: If Mary's age is M now, how old will she be 10 years from now?
: Try again ... what will be the sum of their ages 10 years from now?
: : 5+M + M + 10= 39
: : 2m=24
: : m=12
: : so John is 12+5=17
: : check 12+17+10=39
: : : : : 12) John in 5 years older then Mary. Ten years from now,the sum of their ages will be 39. How old is John now?
: : : : John = J
: : : : Mary = M
: : : : J = 5 + M
: : : : J + M = 39 < ---------- ??
: : : : 5+M + M = 39
: : : : 2M = 34
: : : : M = 17
: : : : so J = 22
: : : : check 17 + 22 = 39
