It seems like you've provided multiple mathematical expressions across lines. To clarify, I see three expressions:

1. \( 7x - 5 \)
2. \( 6 - 5x + 3 \)
3. \( 7 = 2x - 7 \)

Let's break these down individually:

### 1. \( 7x - 5 \)
This is a simple linear expression.

### 2. \( 6 - 5x + 3 \)
This can be simplified:
\[
6 + 3 - 5x = 9 - 5x
\]
This is another linear expression.

### 3. \( 7 = 2x - 7 \)
This is an equation, and we can solve for \( x \):
\[
7 = 2x - 7
\]
Add 7 to both sides:
\[
14 = 2x
\]
Now, divide both sides by 2:
\[
x = 7
\]

Let me know if you'd like further clarification or details.
