Question

1. t ÷ 15 = -3

Explanation:

Step1: Multiply both sides by 15

To solve for \( t \), we multiply both sides of the equation \( t \div 15 = -3 \) by 15. This is because the inverse operation of division is multiplication, and we want to isolate \( t \).
\[
(t \div 15) \times 15 = -3 \times 15
\]

Step2: Simplify both sides

Simplifying the left side, \( (t \div 15) \times 15 \) cancels out to \( t \). On the right side, we calculate \( -3 \times 15 \).
\[
t = -45
\]

Answer:

\( t = -45 \)
