Solution : यहाँ $2 x+5 y-1=0$

$2 x+3 y-3=0$

वज्य-गुणन द्वारा,

$\frac{x}{5 \times(-3)-(-1) \times 3}$=$\frac{y}{(-1) \times 2-2 \times(-3)}$=$\frac{1}{2 \times 3-5 \times 2}$

या $\frac{x}{-15+3}=\frac{y}{-2+6}=\frac{1}{6-10}$

या $\frac{x}{-12}=\frac{y}{4}=\frac{1}{-4} ; \quad \therefore \quad x=\frac{-12}{-4}=3, y=\frac{4}{-4}=-1$.
