1) –6x = 1/3
x = 1/3 / (–6) = –1/18
2) 0,1x = –2,75
x = –2,75 / (0,1) = –27,5
3) 1/3 x = 12
x = 12 / (1/3) = 36
4) 5/7 x = –10/49
x = –10/49 / (5/7) = –2/7
1. х = -1/18
2. х = -27,5
3. х = 36
4. х = -2/7
Пошаговое объяснение:
1. -6х = 1/3
х = 1/3 : (-6)
х = 1/3 * (-1/6)
х = -1/18
2. 0,1х = -2,75
х = -2,75 : 0,1
х = -27,5
3. 1/3х = 12
х = 12 * 1/3
х = 12 * 3/1
х = 36
4. 5/7х = -10/49
х = -10/49 : 5/7
х = -10/49 * 7/5
х = -2/7
