Just substitute the numbers into your equation and see what works. For example, (A)if 6 children are going and there are 22 people, then there must be 16 adults. So, 16(16)+5(6)needs to equal 275. It doesn't, so it is not correct. (B) 16(15)+5(7) if this...

First, subtract 4 from both sides (which you said above) then you have (3/5)a=1. Next, to get the a by itself, multiply both sides by the recripocal of 3/5. That leaves the variable by itself and gives you the answer. Be sure to simplify!
