Hi again Kath;

4y-2x=17

Let's add 2x to both sides...

2x+4y-2x=2x+17

4y=2x+17

Let's divide both sides by 4...

y=(2x+17)/4

y=(2/4)x+(17/4)

y=(1/2)x+(17/4)

2y over 3-x=z

(2y)/(3-x)=z

Let's multiply both sides by (3-x)

(3-x)[(2y)/(3-x)]=z(3-x)

2y=z(3-x)

Let's divide both sides by 2...

(2y)/2=[z(3-x)]/2

y=[z(3-x)]/2
