Verified Answer :

First, distribute to simplify the equation.

-3w = -3w
-34 = -12

-3w + (-12) = -18

Now, isolate the variable.
  
-3w + -12 = -18
          +12     +12

- 18 + 12 --> -6

-3w = -6

-3w/-3 = -6/-3    >>>>>     w = 2

Answer: w = 2

-3(w+4) = -18
⇒ -3w -3*4= -18 (distributive property)
⇒ -3w -12= -18
⇒ -3w= -18+ 12
⇒ -3w= -6
⇒ w= -6/(-3)
⇒ w= 2

Final answer: w= 2~
