Answer :

Sure, let's evaluate the given expression step-by-step. The expression is:

[tex]\[ \frac{-6}{13} - 5 - \frac{1}{-26} \][/tex]

We'll break it down into components and evaluate one step at a time.

### Step 1: Evaluate [tex]\(\frac{-6}{13}\)[/tex]
[tex]\[ \frac{-6}{13} \approx -0.46153846153846156 \][/tex]

### Step 2: Evaluate [tex]\(-5\)[/tex]
[tex]\[ -5 \text{ is a whole number and remains } -5 \][/tex]

### Step 3: Evaluate [tex]\(\frac{1}{-26}\)[/tex]
[tex]\[ \frac{1}{-26} \approx -0.038461538461538464 \][/tex]

### Step 4: Combine all terms
Now we need to combine these terms:

[tex]\[ -0.46153846153846156 - 5 - (-0.038461538461538464) \][/tex]

### Step 5: Simplify the combination
First, simplify inside the parentheses:

[tex]\[ -5 - (-0.038461538461538464) = -5 + 0.038461538461538464 \][/tex]

### Step 6: Add the results
Now add [tex]\(-0.46153846153846156\)[/tex] to the result of [tex]\(-5 + 0.038461538461538464\)[/tex]:

[tex]\[ -0.46153846153846156 + (-5 + 0.038461538461538464) \][/tex]

[tex]\[ = -0.46153846153846156 - 4.9615384615384615 \][/tex]

When these terms are combined, the result is:

[tex]\[ \approx -5.5 \][/tex]

Hence, the value of the expression is:

[tex]\[ -5.5 \][/tex]
