Given 4x-1=3x+3
First, get x on one side.
Do this by adding 1 to both sides.
4x-1+1=3x+3+1
You get: 4x=3x+3
Subtract 3x from both sides: x=3. 
You have to move like kinds to the same side. I then would be 4x-3x=3+1 

Meaning your answer would be 1x=4   So x=4

Check it by replacing.. 4(4)-1 = 3(4)+3
16-1=12+3
15=15
