Oh sorry...I actually have already solved these...I just wanted to make sure they were correct and if I didn't get any replies, oh well. Didn't mean to break any rules.

If all you need is to verify your answers, please post what your choices were and someone will be able to take a look and tell you how you did.

Also, it is customary to separate the left and right sides of an equation by some representative symbol. Something like ---> is commonly used.
