4z=6+2z_{2}-3
Subtract 3 from both sides.
4z=3+2z_{2}
Subtract 3 from 6 to get 3.
4z=2z_{2}+3
The equation is in standard form.
\frac{4z}{4}=\frac{2z_{2}+3}{4}
Divide both sides by 4.
z=\frac{2z_{2}+3}{4}
Dividing by 4 undoes the multiplication by 4.
z=\frac{z_{2}}{2}+\frac{3}{4}
Divide 3+2z_{2} by 4.
6+2z_{2}=4z+3
Swap sides so that all variable terms are on the left hand side.
2z_{2}=4z+3-6
Subtract 6 from both sides.
2z_{2}=4z-3
Subtract 6 from 3 to get -3.
\frac{2z_{2}}{2}=\frac{4z-3}{2}
Divide both sides by 2.
z_{2}=\frac{4z-3}{2}
Dividing by 2 undoes the multiplication by 2.
z_{2}=2z-\frac{3}{2}
Divide 4z-3 by 2.
