Testing Solutions to Equations with Substitution

The video tutorial explains how to solve the equation 5x - 3 = 4x + 3 by testing different values for x. It walks through the process of verifying whether x = 5, x = 6, or x = 7 satisfies the equation. The tutorial demonstrates that x = 6 is the correct solution, as it makes both sides of the equation equal. The video emphasizes understanding the process of testing solutions and verifying results.
