Math Problem Statement
Solution
The system of equations in the image is:
We can solve this system using either substitution or elimination. I'll use the elimination method to find the solution.
Step 1: Multiply equations if needed to align coefficients
We want to eliminate one variable. Let's eliminate by multiplying the first equation by 5 and the second equation by 3, so that the coefficients of become the same.
Step 2: Subtract the equations
Now subtract the second equation from the first to eliminate :
Step 3: Solve for
Step 4: Substitute into one of the original equations
Let's substitute into the first equation:
Final Solution:
The solution to the system is:

Here are 5 related questions to expand on this concept:
- Can you solve the same system using the substitution method?
- What is the graphical interpretation of this system of equations?
- How would the solution change if the second equation was ?
- What would happen if both equations were parallel (e.g., and )?
- How can you tell if a system of equations has no solution or infinite solutions?
Tip: Always check your solution by plugging the values of and back into the original equations to verify that they satisfy both equations.
