Question

Please help me with the following problem.
Solve for Q2:

a-2b[a-2b(Q2)-c]-(Q2)-c

Q2= ?

Answer 1

Your expression is missing something - it can't be solved the way it is written because it isn't equal to anything. For example, solve x + 6...x could be anything since we don't know what x + 6 is equal to. In your first expression, you can combine your Q2 terms and group other like terms, but if it's not equal to anything, then you can't solve forr Q2 or any other variable for that matter.
