Question

for what value p has unique solution in following linear equations, px+2y=5,3x+y=1​

Answer 1

$unique \: solution \: so \: the \: lines \\ \\ are \: coincident \\ \\ \frac{a1}{a2} = \frac{b1}{b2} = \frac{c1}{c2} \\ \\ \frac{p}{3} = \frac{2}{1} \\ \\ p = 6$

Answer 2

Step-by-step explanation:

unique solution so the lines

are coincidence

a1\a2=b1\b2=c1\c2

p\3=2\1

P=6
