Answer:
y-determinant = 2
Step-by-step explanation:
Given the following system of equation:
- x + 2y = 5
- x - 3y = 7
Let's represent it using a matrix:
The y‐numerator determinant is formed by taking the constant terms from the system and placing them in the y‐coefficient positions and retaining the x‐coefficients. Then:
y-determinant = (1)(7) - (5)(1) = 2.
Therefore, the y-determinant = 2
