is the answer to my equation right?
13r/13 = -44/13
no. the third line should read
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.
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.
