For the first one, multiply both sides through by 6 and then by 9, what do you get?

How about just multiply both sides by 18?

I agree that this is a better step towards the answer. I think my step(s) are easier to follow for someone who is new to algebra. The candidate can see the 6 and 9, the 18 might be a mystery!

Well, pretty difficult to help, since we don't know how far Mr Myers can get on his own...

for each equation, multiply every term by the common denominator to clear the fractions. common denominators are ...

1. 18

2. x

3. (m-3)(m+3)

4. (m-5)(m+5)

remember the restrictions on certain values that make the denominator value 0.
