Пошаговое объяснение:
а)
-9х = 36
х = 36 : (-9)
х = -4
б)
-7/12х + 11/12 = 13/18
-7/12х = 13/18 - 11/12
-7/12х = 26/36 - 33/36
-7/12х = -7/36
х = -7/36 : (-7/12)
х = -7/36 * (-12/7)
х = -1/3 * (-1/1)
х = 1/3
в)
(х + 22/25) * 1/3 = -7 1/3
х + 22/25 = -7 1/3 : 1/3
х + 22/25 = -22/3 * 3/1
х + 22/25 = -22/1 * 1/1
х + 22/25 = -22
х = -22 - 22/25
х = -22 22/25
