One more and i should be good, i'm pretty familar with this but i'd like to make sure,

two brothers, bill and eric, are 4 years apart, and bill is the older of the two. if the sum of the boys' ages is 28, how old is bill and how old is eric?

both boys age is unknown, yet we can mark both with say,
x = eric's age
y = bills' age

there are many ways to solve this, but we do know they're 4 years apart, so it'd have to be
x + y4 = ? ,

actually that's off but you understand what i'm !
