Questions & Answers

Q: What is the substitution method for solving simultaneous equations?

The substitution method involves solving one equation for one variable and then substituting that expression into the other equation. This allows us to solve for the remaining variable.

Q: How do you check if the solution to a system of simultaneous equations is correct?

To check the solution, substitute the values of the variables back into the original equations. If both equations are satisfied, then the solution is correct.

Q: What are the key steps in solving simultaneous equations using the substitution method?

The key steps are identifying one equation to solve for one variable, substituting that expression into the other equation, simplifying and solving for the remaining variable, and finally checking the solution.

Q: Can the substitution method be applied to any system of simultaneous equations?

Yes, the substitution method can be applied to any system of simultaneous equations as long as one equation can be solved for one variable in terms of the other.
