Hi,         
Applying the Distributive Principle and combining like terms..
will result in isolating x on one side of the equation, thus solving for x.
  4x+5=3(x-1)  
 | Applying the distributive Principle
  4x + 5 =  3x - 3   
Proceeding to combine like terms and isolate x on one side of the equation
  | subtracting 3x from both sides of the equation
  4x -3x + 5 =  3x -3x - 3  
       x + 5 = -3    
  | Subtracting 5 from both sides of the equation
     x + 5 - 5 = -3 - 5
         x = -8  
Always feel free to post questions of a general nature with an example,
as You did here.
