3(4-3x)=-11
Distribute 3 through the parenthesis you get
12-9x=-11
12-9x=-11
Move constant to the right side and change its sign you get
-9x=-11-12
-9x=-11-12
Calculate the difference
-9x=-23
-9x=-23
Divide both sides os the equation by -9 you get:
X=23/9
*If you want alternative form it would be x=2 5/9,x=2.5 :)
