document.write( "If I am 48 and my grandson is 2 years old how old, in years, will I be when I am 3 times his age. I thought that I would just multiply by 3 but the professor said we do not do that to figure out the problem. I thought that maybe I would be 54 and he would be 16 but then it just did not look right. So I tried again and what I got today was I would be 60 and he would b3 4. I am so lost with this problem. \n" );
