Question

What are the solutions of
15 ≤ 5 - 2(4m + 7)

Answer 1

$15 \leqslant 5 - 2(4m + 7) \\ 15 \leqslant 5 - 8m - 14 \\ 15 \leqslant - 8m - 9 \\ 15 + 9 \leqslant - 8m \\ 55 \leqslant - 8m \\ \frac{55}{ - 8} \leqslant m$

Answer 2

Answer:

[tex]15 \leqslant 5 - 2(4m + 7) \\ 15 \leqslant 5 - 8m - 14 \\ 15 \leqslant -9 - 8m \\ 15 + 9 \leqslant 8m \\ - 24 \leqslant 8m \\ m \leqslant \frac{8}{ - 24 } \\ m \leqslant \frac{1}{ - 3} \\ m \leqslant \frac{ - 1}{3}
