42 = -7 (z - 3)<br><br> z = ?
liubo4ka [24]

Answer:

The answer to your question is z = -3

Step-by-step explanation:

Expand                 42 = -7(z - 3)

                             42 = -7z + 21

Simplify                 7z = -42 + 21

                             7z = -21

Clear z                    z = \frac{-21}{7}

                              z = -3
