Question

6,7,8 помогите пожалуйста даю 35 баллов

Answer 1

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

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

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