Answer:

a). +r

b). -m

c). 4m

Step-by-step explanation:

a). x + (-x) + r

  = x - x + r                                                     ∵ (+) + (-) = -

  = 0 + r

  = +r     Ans

b). 2m + 3m + (-6m)

  = 2m + 3m - 6m                                           ∵ (+) + (-) = -

  = 5m - 6m

  = -m    Ans

c). 2m + (-2m) + 4m

  = 2m - 2m + 4m                                           ∵ (+) + (-) = -

  = 2m + 4m - 2m

  = 6m - 2m

  = 4m    Ans
