3%284z-1%29%2B2%28z%2B8%29=2%28z%2B1%29 Start with the given equation.


12z-3%2B2z%2B16=2z%2B2 Distribute.


13%2B14z=2z%2B2 Combine like terms on the left side.


14z=2z%2B2-13 Subtract 13 from both sides.


14z-2z=2-13 Subtract 2z from both sides.


12z=2-13 Combine like terms on the left side.


12z=-11 Combine like terms on the right side.


z=%28-11%29%2F%2812%29 Divide both sides by 12 to isolate z.

Answer:

So the solution is z=-11%2F12
