To solve the equation \( \frac{4}{5}x - 5 = \frac{1}{4} \), we will complete the steps.

Step 1: Add 5 to both sides of the equation.

\[ \frac{4}{5}x - 5 + 5 = \frac{1}{4} + 5 \]

This simplifies to:

\[ \frac{4}{5}x = \frac{1}{4} + 5 \]

Now, to add \( \frac{1}{4} + 5 \), we write 5 as a fraction:

\[ 5 = \frac{20}{4} \]

So:

\[ \frac{1}{4} + \frac{20}{4} = \frac{21}{4} \]

Thus, we have:

\[ \frac{4}{5}x = \frac{21}{4} \]

Step 2: Divide both sides of the equation by \( \frac{4}{5} \).

To do this, we can multiply by the reciprocal:

\[ x = \frac{21}{4} \div \frac{4}{5} = \frac{21}{4} \cdot \frac{5}{4} = \frac{21 \cdot 5}{4 \cdot 4} = \frac{105}{16} \]

Summarizing:

  1. After adding 5 to both sides, we find: \[ \frac{4}{5}x = \frac{21}{4} \]

  2. After dividing by \( \frac{4}{5} \), we conclude: \[ x = \frac{105}{16} \]

So the final answers are:

  • For \( \frac{4}{5}x = \): \( \frac{21}{4} \)
  • For \( x = \): \( \frac{105}{16} \)
