Explicación paso a paso:

A

Answer 2

1. x = 13 - 5
x = 8

2. 3x - 2x = 6 + 2
x = 8

3. 5x - 4x = 15 - 8
x = 7

4. 7x - 4x = 28 - 13
3x = 15
x = 15 / 3
x = 5

5. x + 2x - x = 8
2x = 8
x = 8 / 2
x = 4

6. 2x - 3x = -8
-x = -8

7. 9x = -10 + 4 - 7
9x = -13
x = -13 / 9

8. x + 3x - 2x = 18 - 5 - 7
2x = 6
x = 6 / 2
x = 3

9. 4x + x - 2x + x = 9 + 8 + 3
4x = 20
x = 20 / 4
x = 5

10. -2x - 3x = - 15 - 1 + 8 - 2
- 5x = - 10
x = - 10 / 5
x = - 2
