Question

7/9 х - 5/18 = - 3 ​

Answer 1

Ответ:

$\frac{7}{9} x - \frac{5}{18} = - 3$

$\frac{7}{9} x = - 3 + \frac{5}{18}$

$\frac{7}{9} x = \frac{5 - 54}{18}$

$\frac{7}{9} x = - \frac{49}{18}$

$x = - \frac{49}{18} \div \frac{7}{9}$

$x = - \frac{49}{18} \times \frac{9}{7}$

$x = - \frac{7}{2}$
