can you help me set up an equation for it

anonymous · Answer

um i guess

anonymous · Answer

N will be younger child 
N+2 will be older child

anonymous · Answer

would the first equation be something like x-y=2 or something like that?

anonymous · Answer

3N + 2(N+2) = 9

anonymous · Answer

do you understand that ?

anonymous · Answer

why are you multiplying the 2?

anonymous · Answer

two times the older child

anonymous · Answer

then why are you adding 2 in parentheses?

anonymous · Answer

N will be younger child... this is the young boy
N+2 will be older child this is the older boy...
*Now I added 2 in parentheses because the older boy is the same age as the younger but 2 years older so... you add 2
