2)x = 4

3)x = 8

4)x = 8,5

5) x = 2

6) x = 2

1) x = -4

2)x = 9

3) x = 6

4)x = 10

5)x = 11

6)x = -4

Пошаговое объяснение:

1) x + 2 = -x + 14

2x = 12

x = 12 ÷ 2

x = 6

2) 2x - 3 = x + 1

x = 4

3) 45 - 2x = 3x + 5

-5x = - 40

x = -40 ÷ -5

x = 8

4) 9x - 32 = 2 + 5x

4x = 34

x = 34 ÷ 4

x = 8,5

5) 4x - 7 = 2x - 3

2x = 4

x = 4 ÷ 2

x = 2

6) 8x - 3 = x + 11

7x = 14

x = 14 ÷ 7

x = 2

1) 4x + 3 = x - 9

3x = -12

x = -4

2) 2x - 19 = 8 - x

3x = 27

x = 27 ÷ 3

x = 9

3) 7x + 3 = 3x + 27

4x = 24

x = 24 ÷ 4

x = 6

4) 3x - 7 = 2x + 3

x = 10

5) 42 - x = 2x + 9

-3x = -33

x = -33 ÷ -3

x = 11

6) 20 + 3x = 4 - x

4x = -16

x = -16 ÷ 4

x = -4
