Question

решите уравнение 5-6x2/x+2=7x/x+2​

Answer 1

а что значит 2/х и 7х/х

Answer 2

$5 - \frac{6x2}{x + 2} = \frac{7x}{x} + 2 \\ 5 - \frac{12x}{x + 2} = 7 + 2 \\ 5 - \frac{12x}{x + 2} = 9 \\ - \frac{12x}{x + 2} = 9 - 5 \\ - \frac{12x}{x + 2} = 4 \\ 12x = - 4(x + 2) \\ 12x = - 4x - 8 \\ 12x + 4x = - 8 \\ 16x = - 8 \\ x = - \frac{1}{2}x = - 0.5$
