Question

решите уравнение 5-6x2/x+2=7x/x+2​

Answer 1

а что значит 2/х и 7х/х

Answer 2

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