Hi all, can someone help me and see if I've done this correct... thanks

They all look fine to me. Good work!

A check to see if you are wrong is to plug in numbers for the variable that make both sides of the original equation equal and then see if those same numbers make the last line equal. Give that a try. That way you'll know if you have the wrong answer.
