Yes, it is, so we
did everything right.
Did that make sense to you? I guess the steps you should take are:
1) Simplify (distribute if necessary)
2) Put like terms with like terms (Put all the terms containing the unknown
on one side of the equals sign with the constants on the other side)
3) Divide or do what you must to simplify
4) Check to make sure your answer makes sense
I hope this helps. Maybe you could do the second example and write back
with your answer. Please write back if you have any other questions.
