Math Problem Statement
Solve the system of linear equations: 3x + 2y = 14 and 2x + 3y = 14.
Solution
The system of linear equations in the image is:
We can solve this system using either the substitution method, the elimination method, or matrix methods. Let's proceed with the elimination method:
- Multiply the first equation by 3 and the second by 2 to align the coefficients of :
- Subtract the second equation from the first to eliminate :
- Solve for :
- Substitute into one of the original equations to find . Using the first equation:
Thus, the solution is:
