Question

If a pair of linear equations 3x+2ky =2 and 2x+5y +1=0 are parallel to each other,then the value of 'K'

Answer 1

Answer:

K=15/4

Step-by-step explanation:

lines are parallel

that means

a1/a2=b1/b2 but not equal to c1/c2

take a1/a2=b1/b2

a1=3

a2=2

b1=2k

b2=5

3/2=2k/5

on cross multiplying we get

4k=15

k=15/4
