Find the error in the problem below

 $19-2k=3k-1$  
    $+3k$    $+3k$  
 $19+1k=-1$  
 $-19\ \ \ \ \ \ \ \ \ \ -19$ 
  $k=-20$  

• They should have divided by 1 for the last step

• They should add 19 instead of subtracting 19

• I can not find an error

• Instead of adding 3k they should subtract 3k
