In this video, we solve a system of equations using substitution when a little rearranging is required first.
This example builds on the basic substitution method by showing how to:
• Rearrange one equation to isolate a variable
• Substitute that expression into the second equation
• Solve step by step without skipping reasoning
• Check the solution
This is a great follow-up to Substitution Example 1 and helps Algebra 1 students gain confidence with substitution when the equation isn’t already set up perfectly.
