Question

решите уравнение : 1)
x - 5/23 = 36/92
2) 4/ 3x -11 = 36/63

Answer 1

1)
$x - \frac{5}{23} = \frac{36}{92} \\ \\ x = \frac{36}{92} + \frac{5}{23} \\ \\ x = \frac{36}{92} + \frac{20}{92} \\ \\ x = \frac{56}{92} \\ \\ x = \frac{14}{23}$
2)
$\frac{4}{3} x - 11 = \frac{36}{63} \\ \\ \frac{4}{3}x = \frac{36}{63} + 11 \\ \\ \frac{4}{3} x = 11 \frac{4}{7} \\ \\ x = \frac{81}{7} \times \frac{3}{4} \\ \\ x = \frac{243}{28} \\ \\ x = 8 \frac{19}{28}$
