If the system of linear equations; px+3y-(p-3)=0,12x+py-p=0 has infinite solution then
p/12 = 3/p = p-3/p
p²= 36 => p = ±6 .
3/p = p-3/p
3p = p²-3p
p²-6p = 0
p(p-6) = 0
p = 0 , p = 6 .
Therefore, p = 6 .
p/12 = 3/p = p-3/p
p²= 36 => p = ±6 .
3/p = p-3/p
3p = p²-3p
p²-6p = 0
p(p-6) = 0
p = 0 , p = 6 .
Therefore, p = 6 .
