Answer:
2kx+4y=20 ⇒ kx+2y=10
3x+6y=30 ⇒ x+2y= 10
k is the coefficient of x, so it is the slope of the line
- when k=1, both equations will be same, then there are many solutions
- when k=0 there is one solution
- when k is anything different, then the lines will be parallel, so no solutions
I’m pretty sure the answer is m= -6/5 I’m not sure tho
7/8 / 2/7 =
7/8 * 7/2 = 49/16 = 3 1/16
