To isolate the variable in the equation -3x - 9 = -27, the first step is to add 9 to both sides. This gives you -3x = -18. What is the next step to isolate the variable?
-3x-9=-27 Add 9 to both side -3x-9+9=-27+9 -3x=-18 divided -3 to each side -3x/-3=-18/-3 x=6 Check: -3x-9=-27 substitute x with 6 -3(6)-9=-27 -18-9=-27 -27=-27. As a result, the next step to isolate the variable is divided -3 to both side. Hope it help!
