    substitute 15 for P and 5 for b 15 = 2(a+5) divide both sides by 2 and subtract 5 to isolate a

    Thank you!.. I am excellent when it comes to solving the problem, but when it comes to figuring out how to make the problem is what gets me.

    word problems are not as difficult as they seem...you basically have to write it out like you read it....using " math " language
