Post your work and someone can explain what you are doing wrong.
First simplify 8/4 and 6/3
and then combine like terms.

helper, its not 8/4 and 6/3. its 2r+8 over 4 = 3r-6 over 3

That is written
(2r+8)/4 = (3r-6)/3
(r+4)/2 = (r-2)
r+4 = 2(r-2)
r+4 = 2r - 4
8 = r
(16+8)/4 =? (24-6)/3
24/4 = ? 18/3
6 = 6 yes, it checks

(2r + 8)/4 = (3r - 6)/3
Yes, you are correct, r = 8.
