(w+5)-5=2w+5
there is no multiple choice give me step by step

(w + 5) - 5 = 2w + 5
   w + 5 - 5 = 2w + 5   (remove bracket cuz unneeded)
              w = 2w + 5   (5 and -5 cancel on left side)
             -w = 5            (subtract 2w on both sides)
              w = -5           (convert -w to w)
 
Therefore w = -5

Proof:

 (w + 5) - 5 = 2w + 5
(-5 + 5) - 5 = 2(-5) + 5
          0 - 5 = -10 + 5
              -5 = -5

Hope I helped :P
