30-7z=10z-4 Start with the given equation.


-7z=10z-4-30 Subtract 30 from both sides.


-7z-10z=-4-30 Subtract 10z from both sides.


-17z=-4-30 Combine like terms on the left side.


-17z=-34 Combine like terms on the right side.


z=%28-34%29%2F%28-17%29 Divide both sides by -17 to isolate z.


z=2 Reduce.
