Q. Solve for z z :\newline−21=0.07z -21=0.07 z \newlinez= z=
  1. question prompt: question_prompt: What is the value of zz in the equation −21=0.07z-21 = 0.07z?
  2. isolate z: First, let's isolate z by dividing both sides of the equation by 0.070.07. So, −21/0.07=z-21 / 0.07 = z.
  3. division: Now, do the division: −21/0.07=−300-21 / 0.07 = -300.
