Questions & Answers

Q: Why do we need to solve linear equations by setting them equal to each other?

By setting them equal to each other, we find the point where the lines represented by the equations intersect, which gives us the solution to the system of equations.

Q: Can we solve the equations by setting them equal to each other regardless of their coefficients?

Yes, we can set them equal to each other as long as we solve both equations for the same variable. The coefficients don't affect this process.

Q: What is the significance of finding the point of intersection?

The point of intersection represents the solution to the system of linear equations, as it satisfies both equations simultaneously.

Q: Can we use different methods to solve systems of linear equations?

Yes, there are various methods, such as substitution, elimination, and graphing. Setting them equal to each other is just one approach.
