- What is the substitution method for solving systems of equations?
- How do you solve systems of equations using substitution?
- How do you find the solution to the system 3x - 2y = 8 and x + 5y = -3 using substitution?
- How do you know which variable to get by itself and substitute when solving systems of equations?
- What are the steps for solving systems of equations using substitution?
- How do you get the value of the other variable in a system of equations?
This video steps through the process of solving a system of equations by substitution, explaining everything as it goes. First, you will learn how to decide which variable to get by itself, then you will learn how to get it by itself, how to replace that variable in the other equation to solve for the second variable, and finally how to use that value to find the first variable. This is a very good explanation of this concept.
