Solve for zz.\newline9z=10z+89z = 10z + 8\newlinez=___z = \_\_\_

Full solution

Q. Solve for zz.\newline9z=10z+89z = 10z + 8\newlinez=___z = \_\_\_
  1. Isolate zz: Isolate zz by moving all zz terms to one side of the equation.\newline9z10z=10z+810z9z - 10z = 10z + 8 - 10z\newline1z=8-1z = 8
  2. Solve for z: Solve for z by dividing both sides by 1-1.\newlinez=81z = \frac{8}{-1}\newlinez=8z = -8
