Answer 2

$\frac{3}{4} ( \frac{1}{2} x + \frac{2}{3} ) = 3x + 2 \times \frac{1}{4} \\ \frac{3}{4 \times 2} x + \frac{3 \times 2}{4 \times 3} = 3x + \frac{2}{4} \\ \frac{3}{8} x + \frac{1 \times 1}{2 \times 1} = 3x + \frac{1}{2} \\ \frac{3}{8} x - 3x = \frac{1}{2} - \frac{1}{2} \\ - 2 \frac{5}{8} x = 0 \\ x = 0$
