Solving Linear Equations with One Variable

The video tutorial explains how to solve algebraic equations involving parentheses. It demonstrates the process of distributing terms, moving variables and constants, and combining like terms through three example problems. The tutorial emphasizes the importance of systematically eliminating parentheses and simplifying equations to find solutions.

What is the first step when solving an equation with parentheses?

• Divide by the numerical coefficient

• Distribute the terms inside the parentheses

• Move all constants to the right

• Combine like terms
