Answer:

  3w + 8 – w = 4w – 2(w – 4)

Step-by-step explanation:

The simplified forms of each of these equations are ...

  • 2w +8 = 2w +8 . . . . . .the identity you're looking for
  • 7m -5 = 7m +7 . . . . . . never true
  • -3y +3 = -3y -6 . . . . . . never true
  • -2v +6 = -2v -6 . . . . . . never true
