To solve an equation you need to have the variables on one side and the numbers on the other.
In order to keep the variable positive, move them to the right side.
13-4x=1-x ← add + 4x to both sides
13-4x+4x=1-x+4x
13-1=1+3x-1 ← subtract 1 from each side
12=3x ←:3 to isolate x
123=3x3
4=x ← this is the solution
