x = (3-7y)/2 make y the subject. I started by multiplying the brackets on the left by 2 but then get all confused so I dont think thats the way to do it any help appreciated....

You're on the right track.
$\displaystyle x=\frac{3-7y}{2}$
Multiply both sides by 2 and you get:
$\displaystyle 2x=3-7y$
All you need to do now is get the 3 to the left side and divide everything by -7. Can you do it?
