How to solve a system of equation using substitution

The video tutorial explains how to solve a system of equations using the substitution method. It begins by identifying a variable to solve for, preferably one with a coefficient of one, to simplify the process. The tutorial demonstrates solving for this variable and substituting it into the other equation. The process involves using inverse operations and combining like terms to find the values of both variables. The tutorial concludes with a recap of the steps involved in solving systems of equations using substitution.

What is the first step in solving the system of equations using substitution?

How do you isolate the variable X in the equation X + 2Y = 8?

What do you do after solving for X in terms of Y?

Explain the process of substituting the value of X back into the original equation.

What is the final value of Y after solving the system of equations?
