Find the values of k for which the following simultaneous equations have no solutions:

2x - 3ky = 1
4x + (k + 2)y = 5

Step-by-step explanation:

The two equations given represent two straight lines in 2-D graph.

The two lines will not intersect if they are parallel.

Hence the two equations will not have solution if the lines are parallel and not coincident.

The condition for 2 lines given by the equations :

ax+by+c=0

dx+ey+f=0 to be parallel but not coincident is:

here a=2  b=-3k  c=-1  d=4  e=k+2  f=-5

But also:

Hence the value of k is -2/7.

show us the graphs dude

step-by-step explanation:

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6

happy to
