Решите линейное уравнение:
а) $\frac{1}{3}x = 12$;
б) $\frac{2}{3}y = 9$;
в) $-4x = \frac{1}{7}$;
г) $5y = -\frac{5}{8}$;
д) $\frac{1}{6}y = \frac{1}{3}$;
е) $\frac{2}{7}x = 0$.
$\frac{1}{3}x = 12$
$x = 12 : \frac{1}{3}$
$x = 12 * \frac{3}{1}$
x = 36
$\frac{2}{3}y = 9$
$y = 9 : \frac{2}{3}$
$y = 9 * \frac{3}{2}$
$y = \frac{27}{2}$
y = 13,5
$-4x = \frac{1}{7}$
$x = \frac{1}{7} : (-4)$
$x = \frac{1}{7} * (-\frac{1}{4})$
$x = -\frac{1}{28}$
$5y = -\frac{5}{8}$
$y = -\frac{5}{8} : 5$
$y = -\frac{5}{8} * \frac{1}{5}$
$y = -\frac{1}{8} * \frac{1}{1}$
$y = -\frac{1}{8}$
$\frac{1}{6}y = \frac{1}{3}$
$y = \frac{1}{3} : \frac{1}{6}$
$y = \frac{1}{3} * \frac{6}{1}$
y = 2
$\frac{2}{7}x = 0$
$x = 0 : \frac{2}{7}$
x = 0
