$\{m\ |\ m\gt-5\}$
Solve the inequality. $13-9m\lt58\longrightarrow$ subtract 13 from each side $13-9m-13\lt58-13\longrightarrow$ subtract $-9m\lt45\longrightarrow$ divide each side by -9; reverse the inequality sign $-9m\div-9\gt45\div-9\longrightarrow$ divide $m\gt-5$ The solution is written in the criteria area of the set-builder notation.
