Q. Solve the equation to find z z .\newline−30−4z=72−2zz= \begin{aligned} -30-4 z & =72-2 z \\ z & = \end{aligned} \newlineSubmit
  1. Add 4z4z: Add 4z4z to both sides to get rid of the −4z-4z on the left side.\newline−30−4z+4z=72−2z+4z-30-4z+4z=72-2z+4z\newline−30=72+2z-30=72+2z
  2. Subtract 7272: Subtract 7272 from both sides to isolate the term with zz.\newline−30−72=72−72+2z-30-72=72-72+2z\newline−102=2z-102=2z
  3. Divide by 22: Divide both sides by 22 to solve for zz.−1022=2z2-\frac{102}{2}=\frac{2z}{2}z=−51z=-51
