First of all, I'd like to thank whoever will be answering my question. I truly appreciate it. Anywho let's get right to it. My question is this: how do i solve equations that say stuff like... a^2(b/8*7)=74 Solve for w. THERE ARE SO MANY QUESTIONS LIKE THIS!!! It gives you a and b then tells you to solve for w. There is no w in the information that they gave you. It's like saying, "greg has 4 plates, bill has 3. Greg gave bill 2 of his plates. How many plates does josh have? You see what I mean? there's SO many questions like that out there so my question is... HOW DO U SOLVE SOMETHING THAT SEEMS TO BE IMPOSSIBLE SUCH AS THESE QUESTIONS???
