3z/2=z/6+4

so

i x multiply and get

18z=2z+8

16z=8

z=1/2

this look right?

thanks

1. Multiply both sides of the equation with 6:

6*(3z/2)=6*(z/6+4)

OR:

18z/2=6z/6+6*4

Or:

9z=z+24

That is:

8z=24

Whereby:

z=3

Note:

I didn't bother with your cross-multiplication; that was an unnecessary operation.
