Solving Linear Equations Concepts

The video tutorial explains how to solve and verify a linear equation in one variable. It begins with an introduction to the concept of solving linear equations by isolating the variable. The tutorial then details the process of simplifying both sides of the equation by clearing parentheses and combining like terms. Next, it covers isolating the variable through addition or subtraction and solving for the variable by division. Finally, the solution is verified by substituting it back into the original equation to ensure correctness.

What is the primary goal when solving a linear equation in one variable?

• To find the sum of all coefficients

• To find the value of the variable that makes the equation true
