3%286z-1%29-4%28z%2B4%29=7%28z%2B1%29 Start with the given equation.


18z-3-4z-16=7z%2B7 Distribute.


-19%2B14z=7z%2B7 Combine like terms on the left side.


14z=7z%2B7%2B19 Add 19 to both sides.


14z-7z=7%2B19 Subtract 7z from both sides.


7z=7%2B19 Combine like terms on the left side.


7z=26 Combine like terms on the right side.


z=%2826%29%2F%287%29 Divide both sides by 7 to isolate z.

Answer:

So the solution is z=26%2F7
