Question

If the pair of equations 2x+3y+k=0, 6x+9y+3-0 having infinite solutions then the value of k=2x+By+k-0, 6x+9y+3-0 రేఖీయ సమీకరణాల జతకు అనంతమైన సాధనలు ఉంటే k: A) 2 B)3 D) 1 Co​

Answer 1

Answer:

Since it has infinitely many solution. so, a1/a2=b1/b2=c1/c2

here a1=2,b1-3 and c1=5 and a2=6, b2=9,c2-k.

now we get 2/6-3/9=5/k.

so 3/9-5/k.

45=3k

k=45/3k=15.

so the value of k is 15
