Answer 1

Explicación paso a paso:

1. 3x = 8+7

3x. = 15

x = 5

2. 6x - 36 = 2x +4

4x = 36 +4

4x = 40

x = 10

3. x+ 6 -3x = 8

-2x = 2

x = -1

4. 3x -3 = 2x - 4x

5x. = 3

x = 3/5

5. 6x + 4 = 6x -3

1

6. 8x = -2/15

x = 1/ 60

7. x/ 6 = -1/3

x = -1 / 18

8. 5x +5 = 2x +4

3x = -1

x = -1 / 3

9. 3x -3. = 4x +8

-11 = x

10. 8x = 3x +3

5x = 3

x = 3/5
