2x-3            4x-2                 6x-2
------   + --------    - 2 =  --------
9               7                        4

We are given the equation:

\[
\frac{2x - 3}{9} + \frac{4x - 2}{7} - 2 = \frac{6x - 2}{4}
\]

To solve this equation, let's go step by step:

### Step 1: Eliminate the fractions
To eliminate the fractions, multiply every term by the least common denominator (LCD) of the denominators \(9\), \(7\), and \(4\). The LCD of 9, 7, and 4 is 252.

Multiply each term by 252:

\[
252 \times \left(\frac{2x - 3}{9}\right) + 252 \times \left(\frac{4x - 2}{7}\right) - 252 \times 2 = 252 \times \left(\frac{6x - 2}{4}\right)
\]

This simplifies to:

\[
28(2x - 3) + 36(4x - 2) - 504 = 63(6x - 2)
\]

### Step 2: Expand the terms
Now, expand each term:

\[
28(2x - 3) = 56x - 84
\]
\[
36(4x - 2) = 144x - 72
\]
\[
63(6x - 2) = 378x - 126
\]

Substituting these into the equation gives:

\[
56x - 84 + 144x - 72 - 504 = 378x - 126
\]

### Step 3: Combine like terms
On the left-hand side:

\[
56x + 144x - 84 - 72 - 504 = 200x - 660
\]

So the equation becomes:

\[
200x - 660 = 378x - 126
\]

### Step 4: Solve for \(x\)
To isolate \(x\), subtract \(200x\) from both sides:

\[
-660 = 178x - 126
\]

Next, add 126 to both sides:

\[
-534 = 178x
\]

Finally, divide by 178:

\[
x = \frac{-534}{178} = -3
\]

### Final Answer:
\[
x = -3
\]
