Math Problem Statement
Solution
The system of equations shown in the image is:
To solve this, we can use the elimination method by adding the two equations together.
- Add the two equations:
So, .
- Substitute into one of the original equations, say the first one:
Thus, the solution is and .
The correct answer is D: "The system of equations has exactly one solution where and ."
Would you like a more detailed explanation, or do you have any further questions?
Here are five related questions to deepen your understanding:
- How can you check if a system of equations has no solution?
- What does it mean when a system of equations has infinitely many solutions?
- How does the substitution method work when solving systems of equations?
- What is the graphical interpretation of solving systems of linear equations?
- Why might elimination be preferred over substitution in some cases?
Tip: Always check your solution by substituting the values back into both original equations to ensure they satisfy both equations.
