1. **Problem Statement:** Make $t$ the subject of the formula. 2. **General Approach:** To make $t$ the subject, isolate $t$ on one side of the equation. 3. **Step-by-step:** - Identify the equation where $t$ appears. - Use algebraic operations such as addition, subtraction, multiplication, division, and inverse operations (like square root, logarithm) to isolate $t$. - Simplify the expression to get $t$ alone. 4. **Example:** If the equation is $y = at + b$, to make $t$ the subject: $$y = at + b$$ Subtract $b$ from both sides: $$y - b = at$$ Divide both sides by $a$: $$t = \frac{y - b}{a}$$ 5. **Explanation:** The key is to perform inverse operations in reverse order of operations to isolate $t$. This method applies to any equation involving $t$.
