Question 1169224

Five years ago, Sam was seven times as old as his nephew, Bert. Now, Sam is only four times as old as Bert. How old is Sam now if the sum of their ages now is 50?
<pre>BEWARE! Every answer this person now gives is WRONG!! Do NOT use any of his answers!! Does 15 and 60 SUM to 50? Is this person for REAL??
You need to do this: {{{cross(system(highlight(b=15),and,highlight(x=60)))}}}
In addition, the phrase "the sum of their ages now is 50" is OVERKILL. It's UNNECESSARY!!
