Questions & Answers

Q: What is the purpose of solving systems of linear equations?

The goal is to find the point where two lines intersect, which represents the solution to both equations.

Q: How does the substitution method work?

It involves solving one equation for X or Y, then substituting that value into the other equation to find the intersection point.

Q: Why is it important to check the solution by substitution?

Verifying the values of X and Y in both equations ensures that the point is the intersection of the two lines.

Q: Can the substitution method be used for any number of linear equations?

Yes, the method can be applied to systems with multiple equations by substituting values systematically.

Summary & Key Takeaways

• Systems of linear equations are solved by finding the intersection point of two lines.

• The substitution method involves solving one equation for either X or Y and then substituting that value into the other equation.

• By finding the values of X and Y, you can confirm that they are the solution to both equations and the point of intersection.
