Math Problem Statement
Solution
The image presents two different methods for solving systems of equations:
-
Elimination Method (left side):
- The system of equations is:
- You would typically eliminate one variable by adding or subtracting the equations after multiplying them if necessary.
-
Substitution Method (right side):
- The system of equations is:
- In substitution, you substitute the expression for from the first equation into the second equation to solve for , and then substitute back into the first equation to find .
Would you like to see the detailed steps for either of these methods or for both?
Here are some questions to explore further:
- What is the first step in solving by the elimination method?
- How can the system of equations be manipulated to eliminate one variable in the elimination method?
- What is the substitution step used to solve for in the substitution method?
- What happens when you substitute into the second equation?
- How do you verify the solution after solving the system?
Tip: Always double-check your solution by substituting the values back into both original equations.
