Question:
$2 x+3 y=10$
$x+6 y=4$
Solution:
Given : $2 x+3 y=10$
$x+6 y=4$
Using Cramer's Rule, we get
$\mathrm{D}=\mid 2 \quad 3$
$1 \quad 6 \mid=12-3=9$
$\mathrm{D}_{1}=\mid 10 \quad 3$
$4 \quad 6 \mid=60-12=48$
$\mathrm{D}_{2}=\mid 2 \quad 10$
$1 \quad 4 \mid=8-10=-2$
Now,
$\mathrm{x}=\frac{\mathrm{D}_{1}}{\mathrm{D}}=\frac{48}{9}=\frac{16}{3}$
$\mathrm{y}=\frac{\mathrm{D}_{2}}{\mathrm{D}}=\frac{-2}{9}$
$\therefore x=\frac{16}{3}$ and $\mathrm{y}=\frac{-2}{9}$
