Step-by-step explanation:

Step 1: Define

Identify

-t = 9(t - 10)

Step 2: Solve for t

[Distributive Property] Distribute 9:                                                                 -t = 9t - 90[Subtraction Property of Equality] Subtract 9t on both sides;                       -10t = -90[Division Property of Equality] Divide -10 on both sides:                               t = 9
