no. the third line should read
15r+r-3r=35-9
is the answer to my equation right?
equation: 5(3r-7)+r=3(r-3)
15r-35+r=3r-9
15r+r-3r=-35-9
13r/13 = -44/13

from the 2nd line, when -35 is transposed to other side,
15r - 35 + r = 3r - 9
15r + r - 3r = 35 - 9
...it must be positive 35. you forgot to change its sign.
15r - 35 + r = 3r - 9
15r + r - 3r = 35 - 9
...it must be positive 35. you forgot to change its sign.
Oh so you are saying that the 35 should be a positive instead of a negative. Is that correct!!So the answer for r is 2. Thanks I think I get it.
