Question

Как решить уровнение 9/24+(x-3/7)=23/28

Answer 1

$\frac{9}{24} + (x - \frac{3}{7} ) = \frac{23}{28} \\ \\ \frac{9}{24} + x - \frac{3}{7} = \frac{23}{28} \\ \\ \frac{3}{8} - \frac{3}{7} \ \\ \ \\ \frac{21 - 24}{56} = \frac{ - 3}{56} = - \frac{3}{56} \\ \\ - \frac{3}{56 } + x = \frac{23}{28} \\ \\ x = \frac{23}{28} + \frac{3}{56} \\ \\ \frac{46 + 3}{56} = \frac{49}{56} = \frac{7}{8} \\ \\ x = \frac{7}{8}$
