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)
$frac{4}{3} x - 11 = frac{36}{63} \ \ frac{4}{3}x = frac{36}{63} + 11 \ \ frac{4}{3} x = 11 frac{4}{7} \ \ x = frac{81}{7} times frac{3}{4} \ \ x = frac{243}{28} \ \ x = 8 frac{19}{28}$
