1. Problem Description

The problem asks us to solve the given equation for xx and then find the real number aa such that x>2x > 2. The equation is
4a23x+3+3a+3x21=2a23x23+3x1\frac{4a^2}{3x+3} + \frac{3a+3}{x^2-1} = \frac{2a^2}{3x^2-3} + \frac{3}{x-1}.

2. Solution Steps

First, we factor the denominators:
3x+3=3(x+1)3x+3 = 3(x+1)
x21=(x1)(x+1)x^2-1 = (x-1)(x+1)
3x23=3(x21)=3(x1)(x+1)3x^2-3 = 3(x^2-1) = 3(x-1)(x+1)
x1=x1x-1 = x-1
So, the equation can be written as:
4a23(x+1)+3a+3(x1)(x+1)=2a23(x1)(x+1)+3x1\frac{4a^2}{3(x+1)} + \frac{3a+3}{(x-1)(x+1)} = \frac{2a^2}{3(x-1)(x+1)} + \frac{3}{x-1}
We multiply both sides of the equation by 3(x1)(x+1)3(x-1)(x+1) to clear the denominators. We assume x1x \ne 1 and x1x \ne -1:
3(x1)(x+1)(4a23(x+1)+3a+3(x1)(x+1))=3(x1)(x+1)(2a23(x1)(x+1)+3x1)3(x-1)(x+1) \left( \frac{4a^2}{3(x+1)} + \frac{3a+3}{(x-1)(x+1)} \right) = 3(x-1)(x+1) \left( \frac{2a^2}{3(x-1)(x+1)} + \frac{3}{x-1} \right)
(x1)(4a2)+3(3a+3)=2a2+33(x+1)(x-1)(4a^2) + 3(3a+3) = 2a^2 + 3 \cdot 3(x+1)
4a2(x1)+9a+9=2a2+9(x+1)4a^2(x-1) + 9a+9 = 2a^2 + 9(x+1)
4a2x4a2+9a+9=2a2+9x+94a^2x - 4a^2 + 9a + 9 = 2a^2 + 9x + 9
4a2x9x=2a2+4a29a4a^2x - 9x = 2a^2 + 4a^2 - 9a
(4a29)x=6a29a(4a^2-9)x = 6a^2 - 9a
x=6a29a4a29x = \frac{6a^2-9a}{4a^2-9}
x=3a(2a3)(2a3)(2a+3)x = \frac{3a(2a-3)}{(2a-3)(2a+3)}
If 2a302a-3 \ne 0, then we can simplify:
x=3a2a+3x = \frac{3a}{2a+3}
We are given x>2x>2. So, 3a2a+3>2\frac{3a}{2a+3} > 2.
3a2a+32>0\frac{3a}{2a+3} - 2 > 0
3a2(2a+3)2a+3>0\frac{3a - 2(2a+3)}{2a+3} > 0
3a4a62a+3>0\frac{3a - 4a - 6}{2a+3} > 0
a62a+3>0\frac{-a-6}{2a+3} > 0
a+62a+3<0\frac{a+6}{2a+3} < 0
6<a<32-6 < a < -\frac{3}{2}
We also need to check the condition 2a302a-3 \ne 0, so a32a \ne \frac{3}{2}. Since 32\frac{3}{2} is not in the range 6<a<32-6 < a < -\frac{3}{2}, we don't need to exclude any values.
Also, we need to make sure that x1x \ne 1 and x1x \ne -1.
If x=1x=1, 3a2a+3=1\frac{3a}{2a+3}=1, so 3a=2a+33a=2a+3, so a=3a=3. This is not in the range 6<a<32-6 < a < -\frac{3}{2}.
If x=1x=-1, 3a2a+3=1\frac{3a}{2a+3}=-1, so 3a=2a33a=-2a-3, so 5a=35a=-3, so a=35a=-\frac{3}{5}. This is not in the range 6<a<32-6 < a < -\frac{3}{2}.

3. Final Answer

6<a<32-6 < a < -\frac{3}{2}
