Given the coincidental lines mx+3y+2=0 and 2x+ny-8=0 what are m and n ?

Given the lines:

mx + 3y + 2
= 0

2x + ny -8 - 0

Given that
both lines are coincidental.

Then the equations of the
lines must be the same.

==> Then the rations should
be equal.

==< m/2 = 3/n =
2/-8

Now we will solve each
variable.

==?> m/2 = 2/-8 =
-1/4

==> 4m= -2 ==? m = -2/4 =
-1/2

Now we will solve for
n.

==> 3/n = 2/-8 =
-1/4

==> -n = 12 ==> n=
-12

Then the values are: m= -1/2  and n=
-12
