Question

Нужно решение уравнений ( не сам ! )​

Answer 1

Пошаговое объяснение:

3)

$\frac{11}{18} - \frac{14}{27}x = \frac{5}{12}$

$\frac{11}{18} - \frac{5}{12} = \frac{14}{27}x$

$\frac{22}{36} - \frac{15}{36} = \frac{14}{27}x$

$\frac{7}{36} = \frac{14}{27} x$

$x = \frac{7}{36} \div \frac{14}{27}$

$x = \frac{7 \times 27}{36 \times 14}$

$x = \frac{3}{8}$

$x = 0.375$

4)

$2 \frac{2}{11} x - \frac{5}{16} = 1 \frac{3}{4}$

$2 \frac{2}{11}x = 1 \frac{3}{4} + \frac{5}{16}$

$2 \frac{2}{11} x = 1 \frac{12}{16} + \frac{5}{16}$

$2 \frac{2}{11}x = 2 \frac{1}{16}$

$x = \frac{33}{16} \div \frac{24}{11}$

$x = \frac{121}{128}$
