Let's solve the equation step-by-step and fill in the gaps.

  1. Start with the original equation: \[ \frac{4}{5}x - 5 = \frac{1}{4} \]

  2. Add 5 to both sides. To do this, convert the 5 to a fraction with a denominator of 4. Thus, \(5 = \frac{20}{4}\). \[ \frac{4}{5}x = \frac{1}{4} + \frac{20}{4} \] This simplifies to: \[ \frac{4}{5}x = \frac{21}{4} \]

  3. To eliminate the fraction, multiply both sides by 5 to obtain: \[ 4x = \frac{21}{4} \times 5 \] This becomes: \[ 4x = \frac{105}{4} \]

  4. Now we can multiply both sides by 5: \[ 45x = 105 \]

  5. Next, divide both sides by 45: \[ x = \frac{105}{45} \]

  6. Reduce \(\frac{105}{45}\): Both 105 and 45 can be divided by 15: \[ x = \frac{7}{3} \]

Summing up the results:

  • For \(45x =\) the answer is \(105\).
  • Therefore, \(x = \frac{7}{3}\).

Final filled responses:

  • \(45x = 105\)
  • \(x = \frac{7}{3}\)
