Answer 1

1. 2х = -2

х = -1

2. -2х = -6

х = 3

3. 2х = 5

х = 2.5

4. 12 - 4х = 2х + 6

6х = 6

х = 1

5. 7+6х+3 = 40

6х = 30

х = 5

Answer 2

Ответ:

Пошаговое объяснение:

1) 2x + 3 = 1
2x = 1 - 3
x = -2\2
x = -1
2) -4x + 6 = -2x
-4x + 2x = -6
-2x = -6
x = -6\-2
x = 3
3) 6 + 4x = 2x + 11
4x - 2x = 11 - 6
2x = 5
x = 5\2
x = 2,5
4) 4(3 - x) = 2x + 6
12 - 4x = 2x + 6
-4x - 2x = 6 - 12
-6x = -6
x = -6\-6
x = 1
5) 7 + 3(2x + 1) = 40
7 + 6x + 3 = 40
6x = 40 - 7 - 3
6x = 30
x = 30\6
x = 5
