А) х/36 = - 4/9 Б) х : 8/16 = - 4/24х = - 4/9 * 36 х = - 4/24 * 8/16 = - (1*1)/(3*4)
х = - 4 * 4 х = - 1/12
х = - 16
В) - 3 1/7х - 2 5/21 = - 4 1/3 - 1 1/21х
- 3 1/7х + 1 1/21х = - 4 1/3 + 2 5/21
- 3 3/21х + 1 1/21х = - 4 7/21 + 2 5/21
- 2 2/21х = - 2 2/21
х = - 2 2/21 : (-2 2/21) = 44/21 : 44/21 = 44/21 * 21/44 = 1 (-) : (-) = (+)
х = 1
