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%28system%28highlight%28b=15%29%2Cand%2Chighlight%28x=60%29%29%29

In addition, the phrase "the sum of their ages now is 50" is OVERKILL. It's UNNECESSARY!!
