To solve the equation [tex]\(9 - 2c = -13\)[/tex], we will use the Properties of Equality and show each step in detail.

### Step-by-Step Solution:

#### 1. Start with the initial equation:
[tex]\[ 9 - 2c = -13 \][/tex]

#### 2. Subtract 9 from both sides of the equation:
[tex]\[ (9 - 2c) - 9 = -13 - 9 \][/tex]

Justification: Subtraction Property of Equality
Subtracting the same number from both sides of an equation keeps the equation balanced.

Simplifying this step:
[tex]\[ -2c = -22 \][/tex]

#### 3. Divide both sides of the equation by -2:
[tex]\[ \frac{-2c}{-2} = \frac{-22}{-2} \][/tex]

Justification: Division Property of Equality
Dividing both sides of an equation by the same nonzero number keeps the equation balanced.

Simplifying this step:
[tex]\[ c = 11 \][/tex]

### Final Answer:
[tex]\[ c = 11 \][/tex]

This is the solution to the equation [tex]\(9 - 2c = -13\)[/tex].
