Question

Ayúdenme con unas ecuaciones:(

Answer 1

Aquí te dejo mi respuesta:

1. |5x - 10| = 15 = x = 5
2. |15x - 10| = 25 = x = 7/3 = 2.33333....
3. 4 + |3x - 10| = 15 = x = 7
4. 20 + |4x - 1| = 15 = x = -1
5. |5x - 20| ≤ 15 = x ≤ 7
6. 8 - 2 |5x - 10| ≤ 15 = x ≥ -17/25 = -0.68
7. -10 - 4 |2x - 10| ≥ 20 = x ≤ -20/21 = -0.95238....
8. |-25x - 100| > 125 = x < -9

Espero haberte ayudado :D
