Below
Step-by-step explanation:
We can just plug in 3 for k and solve :
x - 1 / 3 = 3
Step 1. Multiply both sides by 3
x - 1 = 9
Step 2. Move the -1 to the other side and change the sign
x = 9 + 1
x = 10
We can check to see if this works :
10 - 1 / 3 = k
9 / 3 = k
3 = k so this is correct
Hope this helps!

They are parallel
Step-by-step explanation:
If that is a letter O in the second equation then they are parallel because you can plug in any number for it and if you plug in -0.9 for O then you can see they are parallel.
If that is the number 0 then they are neither parallel or perpendicular they make about a 25 degree angle with each other
