Solution:
1. Simplify the expression on the right side of the equation:
- 3 - \frac{1}{4} = \frac{12}{4} - \frac{1}{4} = \frac{11}{4}

2. Substitute back into the equation:
- 2 - X = 2 \times \frac{11}{4}

3. Calculate the multiplication:
- 2 \times \frac{11}{4} = \frac{22}{4} = \frac{11}{2}

4. Write the equation:
- 2 - X = \frac{11}{2}

5. Make X the subject of the formula:
- Subtract 2 from both sides:
- -X = \frac{11}{2} - 2

6. Convert 2 to a fraction with the same denominator:
- 2 = \frac{4}{2}

7. Continue solving for X:
- -X = \frac{11}{2} - \frac{4}{2} = \frac{7}{2}

8. Multiply both sides by -1 to solve for X:
- X = -\frac{7}{2}
