Master Solving a system of equations by substitution

The video tutorial explains how to solve systems of equations using the substitution method. It covers the basics of substitution, including when to use it, and provides three detailed examples. The tutorial emphasizes the importance of having a variable with a coefficient of 1 or -1 for easier calculations. Each example is solved step-by-step, demonstrating the substitution process and how to find the solution for both variables.

How do you handle equations that do not have a coefficient of 1 when using substitution?

What is the significance of the coefficient of -1 in the equation -X + 3Y = -5?

Explain how to apply the distributive property when substituting values into an equation.

What is the final coordinate point when solving the system of equations with X = -7 and Y = -4?
