Question

6,7,8 помогите пожалуйста даю 35 баллов

Answer 1

$6. frac{3-3}{3} =0\\ frac{1-3}{1} =-2\\ frac{-1-3}{-1} =4$

$7.a)x-2 = 2(x-1)\ x-2 = 2x - 2\ x = 0\ b) x-2 = 0(x-1)\ x-2 = 0\ x = 2\ c) x-2 = -(x-1)\ x - 2 = -x + 1\ 2x = 3\ x = 1,5\ d) x-2 = 0,5(x-1)\ x-2 = 0,5x - 0,5\ 0,5x = 1,5\ x = 3$

$8. 1)frac{x}{x-1} \ 2) frac{x-3}{2x+4}$
