Rearrange multi-variable equations

Rearranging multi-variable equations, also known as solving for a variable, is a crucial skill in science and math. It allows you to solve for any variable in a formula.

Lesson 3

Concept

**Example:** Solve the formula for the area of a trapezoid, A = (1/2)h(b₁ + b₂), for h. 1. **Multiply by 2:** 2A = h(b₁ + b₂) 2. **Divide by (b₁ + b₂):** 2A / (b₁ + b₂) = h
