6=-3 (x+2) I have to combine and do something but I just dont understand it

6=-3 (x+2)

--Distribute - 3 (x+2)

6=-3x-6

--Flip the equation

-3x-6=6

--add 6 on both sides ... the 6's will cancel each other and 6+6=12

-3x=12

--divide - 3 on both sides ... the 3's will cancel each other and 12 divided by - 3 = - 4

Answer: x = - 4
