5/(x+1)-5/2=2/(3x+3)
5- 5(x+1)/2 = 2/3
5-(5x+5)/2 = 2/3
4 1/3 = (5x+5)/2
8 2/3 = 5x+5
3 2/3 = 5x
11/3 = 5x
11/15 = x

if you are solving for x then,
Rewrite the equation as 5/(x + 1) - (5/2) = 2/3(x+1)
add (5/2) to both sides
5/(x +1) = 2/3(x+1) -(5/2)
subtract 2/3(x +1) from both sides
5/(x+1) - 2/3(x + 1) = 5/2
mulitiply the first term by 1 or 3/3
that give you a common denominator and a workable equation of
(15 - 2)/(3x + 3) = 5/2
I hope this helps. I will leave you the final bits.

5/(x + 1) - 5/2 = 2/(3x + 3)
5/(x + 1) - 5/2 = 2/(3(x + 1)
multiplying with (x + 1)
5 - 5(x + 1)/2 = 2/3
multiplying with 2
10 - 5x - 5 = 4/3
5 - 5x = 4/3
5x = 5 - 4/3
= 11/3
x = 11/15

5/(x+1) -5/2 = 2/(3x+3)
you can think of (3x+3) as 3(x+1)
Multiply each term by the common denominator of 6(x+1)
5*6(x+1)/(x+1) - 5*6(x+1)/2 = 2*6(x+1)/3(x+1)
30 - 15(x+1) = 4
30 - 15x - 15 = 4
11 = 15x
11/15 = x
Check to ensure you're not dividing by zero
(11/15 +1) is not zero, so the answer stands.

5/(x+1) - 5/2 = 2/(3x+3)
(2*5 - 5(x+1))/2(x+1) = 2/3(x+1)
(10 - 5(x+1))/2 = 2/3 ----> as (x+1) in both the denomenators cancel each other
(10-5x-5) /2 = 2/3
3*(5-5x)= 2*2 ---> cross multiply
15 -15x = 4
-15x =4-15
-15x = -11
(Multiply by -1 and divide by 15)
x = 11/15

5/(x+1)-5/2=2/(3x+3)
5/(x+1) - (2/3)/(x+1) = 5/2
(5 - 2/3)/(x+1) = 5/2
(13/3) = (5/2)(x+1)
x +1 = (13/3)(2/5) = 26/15
x = -1 + 26/15 = 11/15

Hey come on kid do your own home work it is very easy.
Try to find x first then it is easy from there
