The inequality 5x−23−7x−35>x4\frac{5x - 2}{3} - \frac{7x - 3}{5} > \frac{x}{4} holds when

Solution

✅ Correct Option: 2

The inequality is 5x−23−7x−35>x4\frac{5x - 2}{3} - \frac{7x - 3}{5} > \frac{x}{4}

The LCM of the denominators 3, 5, and 4 is 60.

Multiply every term by 60:

60×5x−23−60×7x−35>60×x460 \times \frac{5x - 2}{3} - 60 \times \frac{7x - 3}{5} > 60 \times \frac{x}{4}

20(5x−2)−12(7x−3)>15x20(5x - 2) - 12(7x - 3) > 15x


Expand:

100x−40−84x+36>15x100x - 40 - 84x + 36 > 15x


Combine like terms:

16x−4>15x16x - 4 > 15x


Solve for xx:

16x−15x>416x - 15x > 4

x>4x > 4

Therefore, x∈(4,∞)x \in (4, \infty)
