16%28z%2B3%29=4%28z%2B9%29 Start with the given equation.


16z%2B48=4z%2B36 Distribute.


16z=4z%2B36-48 Subtract 48 from both sides.


16z-4z=36-48 Subtract 4z from both sides.


12z=36-48 Combine like terms on the left side.


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


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


z=-1 Reduce.

Answer:

So the solution is z=-1
