2r + 4 or 2*(r+2)
9r-1?
It is not correct to say that 8 plus 2 8r-2r 4 3r plus 2 r = 0
(r + 1)(2r + 5)
-6r - s
2r + 4 or 2*(r+2)
|2r + 9| = 5 So 2r + 9 = 5 or 2r + 9 = -5 so that 2r = -4 or 2r = -14 r = -2 or r = -7
2r + 7r - 6t - r + 7t = 8r + t
4r+4g
9r-1?
It is not correct to say that 8 plus 2 8r-2r 4 3r plus 2 r = 0
5(2r + 5)
r -31
It is 4r + 12s
10+r = 2r Subtract r from both sides:- r = 10
(r + 1)(2r + 5)
-6r - s
