Q1.

Solve the system of linear equations using Cramer's Rule:

3x + 2y = 12

2x + 3y = 13

🇳🇵 क्रेमर्सको नियम (Cramer's Rule) प्रयोग गरी समीकरण हल गर्नुहोस्: $$3x + 2y = 12$$ $$2x + 3y = 13$$

NEB Board Strategy: Calculate $D$, $D_1$, and $D_2$ clearly before computing $x = D_1/D$ and $y = D_2/D$.
