You want to isolate the variable x to one side of the equation. Add 6 to both sides first:

-4x-3x = 11 (6+5)

Then add the two variables together since they are similar variables = -7x

Lastly, divide x by -7 and then do the same to the other side of the equation:

-7x/-7 = 11/-7

then you'll be left with x = -1.57. Plug -1.57 back into the original equation to check your answer.
