Use a calculator to evaluate the left and right side separately.

4/3 = 24/30
1.333 = 0.8

The equation is false.

----------------------------------

Alternatively, you can cross multiply like so

4/3 = 24/30
4*30 = 3*24
120 = 72

Since that equation is false, it means that the original equation 4/3 = 24/30 is false.

<u>Step 2: Solve for </u><u><em>z</em></u>

  1. Distribute negative:                      -21 = z + 6 + 2z
  2. Combine like terms:                     -21 = 3z + 6
  3. Isolate <em>z</em> term:                               -27 = 3z
  4. Isolate <em>z</em>:                                        -9 = z
  5. Rewrite:                                         z = -9
