Ответ:

Пошаговое объяснение:

1. 5x - 3 = 3x + 5

2x = 8

x = 4

2. 2x = 18 - x

3x = 18

x = 6

3. 2x + x + (2x - 5) = 110

5x - 5 = 110

5x = 115

x = 23

4. 7 + 2x = 3x - 18

-x = -25

x = 25

5. 10x - 7 = 6x + 13

4x = 20

x = 5

6. x + 4x = 215

5x = 215

x = 43

7. x + x + 9 = 43

2x = 34

x = 17

8. x + 2x + x + 14 = 250

4x + 14 = 250

4x = 236

x = 59

9. x + 17 = 4x - 25

3x = 42

x = 14

10. 12x = 8(x + 12)

12x = 8x + 96

4x = 96

x = 24
