I can solve the problems if I have the expression, but can't figure out how to get the problem?  Example : The sum of 2 brothers' ages is 38.  One brother is 10 years older than the other.  How old is each brother?  Example 2:  Matthew loaned three friends a total of $27.  All he can remember is that he loaned the second friend $5 more than the first and the third friend twice as much as the second.  How much did he loan each of the 3 friends?  Any help would be greatly appreciated.  thanks! </SPAN>\n" );
