Post your work and someone can explain what you are doing wrong.

First simplify 8/4 and 6/3

and then combine like terms.

**I HATE MATH!!!**, Saturday, January 22, 2011 at 6:20pmhelper, its not 8/4 and 6/3. its 2r+8 over 4 = 3r-6 over 3

**Damon**, Saturday, January 22, 2011 at 6:24pmThat is written

(2r+8)/4 = (3r-6)/3

(r+4)/2 = (r-2)

r+4 = 2(r-2)

r+4 = 2r - 4

8 = r

check

(16+8)/4 =? (24-6)/3

24/4 = ? 18/3

6 = 6 yes, it checks
