Question

а) 2/×-2/=2:
b) 12/3×-5=-200​

Answer 1

а)

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

$\frac{4}{x} - 5 = - 200 \\ \\ \frac{4}{x} = - 200 + 5 \\ \\ \frac{4}{x} = - 195 \\ \\ 4 = - 195x \\ \\ - 195x = 4 \\ \\ x = - \frac{4}{195}$
