-2x = -6
-2x + 2x = -6 + 2x
0 = -6 + 2x
6 = 2x
x = 3
-6x = 2
-6x ÷ (-6) = 2 ÷ (-6)
x = -2/6
x = -1/3
3,5x = -7
3,5x ÷ 3,5 = -7 ÷ 3,5
x = -2
-0,1x = 10
-0,1x ÷ (-0,1) = 10 ÷ (-0,1)
x = -100
Пошаговое объяснение:
1)
-2х = -6
х = -6 : (-2)
х = 3
2)
-6х = 2
х = 2 : (-6)
х = -2/6
х = -1/3
3)
3,5х = -7
х = -7 : 3,5
х = -2
4)
-0,1х = 10
х = 10 : (-0,1)
х = -100
