Solution
I see you've uploaded an image of a system of linear equations (SPLDV) solution. Let's break down the process:
-
The given system of equations is:
-
The steps show that you multiplied the second equation by 4 to eliminate , which results in:
- (from multiplying the first equation by 2)
- (from multiplying the second equation by 4)
-
Then, you subtracted the two equations:
- This simplifies to , so .
-
You substituted back into the first equation to solve for :
- Multiplying through by 7 gives , so , and finally .
-
Therefore, the solution is and , as shown at the end.
Yes, the solution is correct. Let me know if you'd like more detailed clarification on any of the steps.
Here are five related questions:
- How would the solution change if both equations were multiplied by different numbers initially?
- Can this system of equations be solved using the substitution method?
- What are some applications of solving systems of equations in real life?
- How can you verify if your solution is correct?
- What happens if both equations are dependent (have infinite solutions)?
Tip: Always double-check your solution by substituting the values of and back into the original equations to verify correctness.
