Step-by-step explanation:

7.

[tex]7 + \frac{m}{8} = - 2 \\ \frac{m}{8} = - 2 - 7 \\ \frac{m}{8} = - 9 \\ m = - 9 \times 8 \\ = - 72[/tex]

8.

[tex] \frac{ - 1}{5} k + 1 = 11 \\ \frac{ - k}{5} + 1 = 11 \\ \frac{ - k}{5} = 11 - 1 \\ \frac{ - k}{5} = 10 \\ - k = 10 \times 5 \\ - k = 50 \\ k = - (50) \\ = - 50[/tex]

9.

[tex] - 6 + \frac{1}{3} w = 0 \\ \frac{1}{3} w = 0 + 6 \\ \frac{1}{3} w = 6 \\ w = 6 \div \frac{1}{3} \\ = 6 \times 3 \\ = 18[/tex]
