Question

If the given pair of linear equations 3x + 2y - k = 0 and 6x + 4y -8 = 0 has infinitely many solutions then the value of k is
.

Answer 1

Step-by-step explanation:

3x + 2y - k = 0 and 6x + 4y -8 = 0 has infinitely many solutions

so a1/a2=b1/b2=c1/c2

3/6=2/4=-k/-8

1/2=1/2=k/8

by cross

k=4
