What you want to do is isolate the variable. Take your equation 3u=14-4u and move the -4u over to the other side; making it look like this 7u=14. Then divide by 7 to isolate the u making u=2. Your answer is u=2.
I think there's missing parts to it, but I'll work with what I have.
4x=3 is not a linear function because there is no y.
Only the slope is given and the slope alone is not a linear function only a mere part of it.
So the function is x= 3/4 not linear
