Applying substitution to solve a system of equations with a consistent independent solution

The video tutorial demonstrates how to solve a system of equations using the substitution method. It begins by explaining the importance of choosing a variable with a coefficient of 1 for substitution. The instructor then shows how to substitute this variable into the other equation and solve for the remaining variable. The distributive property is applied to simplify the equation, leading to the determination of the solution set. The tutorial concludes by summarizing the consistent independent solution obtained.

After finding the value of Y, how do you find the value of X?
