Let's solve the problems shown in the image one by one.

### Problem 5:
\[
6 - 5x = 1 - 4x
\]
- Move all the \( x \)-terms to one side and the constants to the other side.
\[
6 - 1 = 5x - 4x
\]
\[
5 = x
\]
So, the solution is:
\[
x = 5
\]

### Problem 7:
\[
16 - 3 + 7x - 3x = 6x - 1
\]
- First, simplify both sides:
\[
13 + 4x = 6x - 1
\]
- Move all \( x \)-terms to one side and the constants to the other:
\[
13 + 1 = 6x - 4x
\]
\[
14 = 2x
\]
\[
x = \frac{14}{2} = 7
\]
So, the solution is:
\[
x = 7
\]

### Problem 9:
\[
r + 3 + 4 + 11 = -r - 4r
\]
- Simplify both sides:
\[
r + 18 = -5r
\]
- Move all \( r \)-terms to one side:
\[
r + 5r = -18
\]
\[
6r = -18
\]
\[
r = \frac{-18}{6} = -3
\]
So, the solution is:
\[
r = -3
\]
