What is the reason for each step in the solution of the equation?

4x-1=-2 (x+1)

4x-1=-2x-2

6x-1=-2

6x=-1

x=-16

4x-1=-2 (x+1)

4x-1=-2x-2 distribute the - 2

6x-1=-2 add 2x to both sides

6x=-1 add 1 to both sides

x=-16. this step is incorrect

the last step should be dividing both sides by 6,

so the answer should be x=-1/6
