Question

Как решить X-3\2+x\7=1

Answer 1

$\frac{x - 3}{2} + \frac{x}{7} = 1 \\ \frac{7(x - 3)}{14} + \frac{2x}{14} = \frac{14}{14} \\ \frac{7x - 21}{14} + \frac{2x}{14} - \frac{14}{14} = 0 \\ \frac{7x - 21 + 2x - 14}{14} = 0 \\ \frac{9x - 35}{14} = 0 \\ 9x - 35 = 0 \\ 9x = 35 \\ x = \frac{35}{9}$
