Решите уравнение:
а) −5x = 16;
б) $2x = \frac{1}{5}$;
в) $\frac{1}{3}x = 4$;
г) 4x = −2;
д) 0,6x = 3;
е) −0,7x = 5.
−5x = 16
$x = -\frac{16}{5}$
x = −3,2
$2x = \frac{1}{5}$
$x = \frac{1}{5} : 2$
$x = \frac{1}{5} * \frac{1}{2}$
$x = \frac{1}{10} = 0,1$
$\frac{1}{3}x = 4$
$x = 4 : \frac{1}{3}$
$x = 4 * \frac{3}{1}$
x = 12
4x = −2
$x = -\frac{2}{4}$
$x = -\frac{1}{2} = -0,5$
0,6x = 3
$x = \frac{3}{0,6}$
$x = \frac{30}{6}$
x = 5
−0,7x = 5
$x = -\frac{5}{0,7}$
$x = -\frac{5}{1} * \frac{10}{7}$
$x = -\frac{50}{7} = -7\frac{1}{7}$
