Exercise 12.1 Q6 (taken as) $5x - 2y = 6,\; 3x - y = 2$ , has solution $(x, y)$ —

a $(-2, -8)$
b $(2, 8)$
c $(-2, 8)$
d $(2, -8)$

ব্যাখ্যা

Note: the marked key appears incorrect. Solving $3x-y=2 \Rightarrow y=3x-2$ and substituting into $5x-2y=6$ gives $5x-2(3x-2)=6 \Rightarrow -x+4=6 \Rightarrow x=-2,\ y=-8$ . The actual solution is $(-2,-8)$ (option a), which satisfies both equations, not $(2,8)$ .
