Isolate Variable Term: Isolate the variable term on one side of the inequality.−31≤−74−sAdd 74 to both sides to isolate −s.−31+74≤−74+74−s43≤−s
Addition to Isolate s: Now, we need to solve for s, not −s. To do this, we multiply both sides by −1. Remember that when we multiply or divide both sides of an inequality by a negative number, we must reverse the inequality sign.43×(−1)≥−s×(−1)−43≥s
