Solving Linear Equations: A Step-by-Step Approach

This video tutorial reviews solving linear equations in one variable, building on previous lessons about the addition and multiplication properties of equality. It introduces a four-step method to solve any linear equation of the form ax + B = C, where a is not zero. The method involves simplifying each side, moving variable terms to one side and constants to the other, isolating the variable, and checking the result. The tutorial includes three examples demonstrating the method in action, ensuring students understand how to apply the steps to solve equations accurately.
