Question

Resuelve las siguientes ecuaciones

Answer 1

Explicación paso a paso:

1. ...
2. $2x - 3 = - x - 9 \\ 3x = - 6 \\ x = - 2$
3. ...
4. $3 = 5x - 12 \\ 15 = 5x \\ x = 3$
5. ...
6. $- 3x - 11 = x + 5 \\ - 4x = 16 \\ x = - 4$
7. ...
8. $8x - 30 = 2x - 6 \\ 6x = 24 \\ x = 4$
9. ....
10. $11x - 15 = 12 + 2x \\ 9x = 27 \\ x = 3$
11. ....
12. $x + 13 = 43 - 14x \\ 15x = 30 \\ x = 2$
13. ....
14. $2 - 3x = 14 \\ - 3x = 12 \\ x = - 4$
15. ....
16. $5x + 7 = 32 \\ 5x = 25 \\ x = 5$
17. .....
18. $- 4x - 2 = 18 \\ - 4x = 20 \\ x = - 5$
