Sorry about this guys, you'll probably find it pretty easy so you can help me.

I've just got a mental block:

Use Algebraic Equations to solve the following. Let the number be represented by n.

a) George is thinking of a number. When he adds nine to half of the number, the result is 54.

What was the number George was thinking of?

b) If five is taken from a number and then the result is doubled, the answe is six. What was the number?

c) Five more than a number is equal to three times one less than the number. What is the number?
