$m\leq-3$
$15\leq5-2(4m+7)$ $15\leq5-8m-14$ Add 14 to each side $15+14\leq5-8m-14+14$ $29\leq5-8m$ Subtract 5 from both sides: $29-5\leq5-5-8m$ Simplfy: $24\leq-8m$ Divide both sides by -8 (reverse both sides): $\frac{24}{-8}\leq\frac{-8m}{-8}$ Simplify: $-3\geq m$ Let's check: let m=-6 $15≤5−2(4(-6)+7)$ $15\leq39$ Statement is true
