Answer 1

see here u have
(10r + 9 ) - (12r - 5) = 10r + 9 - 12r + 5 = 10r - 12r + 9 - 5 = -2r + 4
take 2 as common in -2r + 4 expression u would get:
2(-1r + 2) or -2(r + 2)

Answer 2

Answer 4

10r+9-12r+5 = -2r+14

Answer 5

You can just think of it like this..

From 10 r you are subtracting 12 r, and from 9 ones you are subtracting -5 ones.

Just do the operation for each type separately, and the result will be the sum of the results of each.
