To determine the number of solutions for each equation, let's analyze them one by one.

1. **Equation: \(7x + 5 = 7x - 5\)**

Subtract \(7x\) from both sides:
\[
5 = -5
\]
This statement is false, indicating that there are no solutions.
- **Zero Solutions**

2. **Equation: \(3x + 6 = -3x - 6\)**

Adding \(3x\) to each side gives:
\[
6 + 6 = -3x + 3x \implies 12 = 0
\]
This is also false, so there are no solutions.
- **Zero Solutions**

3. **Equation: \(3x + 6 = 6 + 3x\)**

Subtracting \(3x\) from both sides results in:
\[
6 = 6
\]
This is a true statement and holds for all values of \(x\), indicating that there are infinitely many solutions.
- **Infinite Solutions**

4. **Equation: \(3x + 6 = 3x + 7\)**

Subtracting \(3x\) from both sides results in:
\[
6 = 7
\]
This statement is false, indicating no solutions.
- **Zero Solutions**

**Final Summary:**

- \(7x + 5 = 7x - 5\): Zero Solutions
- \(3x + 6 = -3x - 6\): Zero Solutions
- \(3x + 6 = 6 + 3x\): Infinite Solutions
- \(3x + 6 = 3x + 7\): Zero Solutions

To solve the equation \(-2x + 20 = 7\), we will follow these steps:

1. **Isolate the term with \(x\)**:

\[-2x + 20 = 7\]

Subtract 20 from both sides:

\[-2x = 7 - 20\]

\[-2x = -13\]

2. **Solve for \(x\)**:

Divide both sides by -2:

\[x = \frac{-13}{-2}\]

\[x = \frac{13}{2} \]

Thus, the solution is:

\[ x = \frac{13}{2} \] or 6.5 in decimal form.

To solve the equation \(2z + 10 + 6z + 14 = -56\), we will follow these steps:

1. **Combine like terms on the left side**:

\[
2z + 6z + 10 + 14 = -56
\]

Combine \(2z\) and \(6z\):

\[
(2z + 6z) + (10 + 14) = -56
\]

Which simplifies to:

\[
8z + 24 = -56
\]


2. **Isolate the term with \(z\)**:

Subtract 24 from both sides:

\[
8z = -56 - 24
\]

\[
8z = -80
\]

3. **Solve for \(z\)**:

Divide both sides by 8:

\[
z = \frac{-80}{8}
\]

\[
z = -10
\]

Thus, the solution is:

\[
z = -10
\]

Let's break down the three tasks you provided one by one.

### 1. Equation with Infinite Solutions
The original equation is:
\[
4(6x + 2) - 6 =
\]
To achieve infinite solutions, you can set the left side equal to itself, which means you can multiply through by a non-zero constant. Here’s an example:

\[
4(6x + 2) - 6 = 4(6x + 2) - 6
\]

This is always true, so it has infinite solutions.

### 2. Equation with Zero Solutions
The given equation is:
\[
5(6x + 7) - 6 =
\]
To create an equation with zero solutions, you can set the left side equal to a false statement. Here's an example:

\[
5(6x + 7) - 6 = 10
\]

Now, if you compute the left side:
\[
5(6x + 7) - 6 = 30x + 35 - 6 = 30x + 29
\]

Now set it to equal 10:
\[
30x + 29 = 10
\]

This results in \(30x = 10 - 29 = -19\), which means you can solve for \(x\). However, if we adjust it slightly to:
\[
5(6x + 7) - 6 = 5(6x + 7) - 2
\]
This leads to no solutions since the two sides are not equal.

### 3. Finding \( x \) for Exactly 1 Solution
The equation given is:
\[
5(4x + 8) = 16x + 4
\]
First, expand the left side:
\[
20x + 40 = 16x + 4
\]

Now, isolate \(x\):
\[
20x - 16x = 4 - 40
\]
\[
4x = -36
\]
\[
x = -9
\]

So the value of \(x\) that makes the equation have exactly one solution is:
\[
x = -9
\]

### Summary of Answers
1. Infinite solutions:
\[
4(6x + 2) - 6 = 4(6x + 2) - 6
\]
2. Zero solutions:
\[
5(6x + 7) - 6 = 10
\]
3. Value of \(x\) with exactly 1 solution:
\[
x = -9
\]
