Explicación paso a paso:
no entendí eso de y calcula el mayor valor entero... :V
5(x – 1) – 8 ≤ 3(x – 1)
5x – 5 – 8 ≤ 3x – 3
5x -13 ≤ 3x – 3
- 3x + 5x ≤ – 3 - 13
2x ≤ -16
x ≤ -16/2
x ≤ -8
Respuesta:
x<5
Explicación paso a paso:
5(x-1)-8 < 3(x-1)
5x-5-8 < 3(x-1)
5x-13 < 3 (x-1)
5x-13 < 3x-3
5x-13-3x < -3
2x-13 < -3
2x < -3+13
2x < 10
x < 10/2
x < 5
