Distribute −1: Distribute −1 across the parentheses in the inequality -1(t - 15) - 13 < -12.-1 \times t + (-1) \times (-15) - 13 < -12-1t + 15 - 13 < -12
Combine like terms: Combine like terms on the left side of the inequality. −1t+15−13=−1t+2So, the inequality becomes -1t + 2 < -12.
Isolate variable term: Isolate the variable term by subtracting 2 from both sides of the inequality.-1t + 2 - 2 < -12 - 2-1t < -14
Divide to solve: Divide both sides of the inequality by −1 to solve for t. Remember that dividing by a negative number reverses the inequality sign.-1t / -1 > -14 / -1t > 14
