Best answer
दी गई रेखाएँ है :
`2x+y-3=0`
`5x+ky -3 =0 `
`3x-y-2=0`
समीकरण (i ) तथा (iii ) को हल करने पर ,
`x=y=1`
अर्थात दोनों रेखाओ का प्रतिच्छेद बिंदु (1 ,1 ) है ।
चुकि प्रश्नानुसार तीनो दी गयी रेखाएँ संगामी है
, अर्थात समीकरण (ii ) से ,
`5x+ky-3 =0 `
इसमें x तथा y के मान रखने पर ,
`5+k-3=0`
`k+2=0`
`k=-2`
