Answer 1

Ответ:

$\frac{2}{x} = 5 \\2 = 5x \\ x = 0.4$

$\frac{2x - 3}{3} = \frac{x + 1}{6} \\ 4x - 6 = x + 1 \\ 4x - 6 + 6 = x + 1 + 6 \\ 4x = x + 7 \\ 3x = 7 \\ \frac{3x}{7} = \frac{7}{3} \\ x = \frac{7}{3}$

$\frac{x}{2} + \frac{x}{3} = 2 \\ \frac{5x}{6} = 2 \\ x = \frac{12}{5} = 2.4$

$0.5(3x - 4) = \frac{(x + 1)}{4} \\ 2(3x - 4) = x + 1 \\ 6x - 8 = x + 1 \\ 5x = 9 \\ x = 1.8$
