Solution
The system of equations provided is:
To solve by elimination, let's eliminate or . Here’s how:
-
Multiply the second equation by to align the -terms for elimination:
-
Now, add these equations together:
-
Substitute back into the second original equation:
Thus, the solution is:
Would you like more details on any step, or do you have further questions?
Follow-Up Questions:
- How does elimination compare to substitution when solving systems of equations?
- What are some tips for choosing which variable to eliminate first?
- How would this solution change if the system had no solution or infinite solutions?
- Can we verify the solution by substituting the values back into both equations?
- What are other methods to solve systems of equations, and when are they preferred?
Tip: Always check your solution by plugging it back into the original equations to ensure it satisfies both.
