This is the third time im asking this question, and i still dont understand

anonymous · Answer

well start with N = J + 16  then J = B+10   then B + J + N = 66 ( the letters are the first names of the boys).  Now use a powerful mathematical tool known as subsititution!

anonymous · Answer

what is that. thats the thing i never got

anonymous · Answer

okay look at N = J + 16 ,  we know that J = B+10 right?

anonymous · Answer

yeah

anonymous · Answer

so in N = J + 16, replace J. we know J = B+10 so we just put that were J is.  N = (B+10) +16

anonymous · Answer

okay..

anonymous · Answer

so now we know N = B +10+16 and we know J = B+10 so go back to J+B+N = 66 and put in what J and N  equal in terms of B, solve for B

the more you practice the easier it becomes and then it'll be just as easy as adding 1+1
