Answer 1

$\frac{1}{2} ( \frac{x}{3} - 1) - 2 = 0 \\ \frac{x}{6} - \frac{1}{2} - 2 = 0 \\ 6( \frac{x}{6} - \frac{1}{2} -2 ) = 0 \times 6 \\ x - 3 - 12 = 0 \\ x - 15 = 0 \\ x = 15$

$\frac{3x}{5} - \frac{2x}{3} + \frac{1}{5} = 0 \\ 15( \frac{3x}{5} - \frac{2x}{3} + \frac{1}{5} ) = 15 \times 0 \\ 3 \times 3x - 5 \times 2x + 3 = 0 \\ 9x - 10x + 3 = 0 \\ - x + 3 = 0 \\ 3 = x$

$\frac{x}{2} - \frac{5}{3} = \frac{3x}{4} \times \frac{1}{12} \\ 6( \frac{x}{2} - \frac{5}{3} ) = 12( \frac{3x}{4} \times \frac{1}{12} ) \\ 3x - 2 \times 5 = 3 \times 3x \\ 3x - 10 = 9x \\ - 10 = 9x - 3x \\ - 10 = 6x \\ - \frac{10}{6} = x \\ - \frac{5}{3} = x$
