Respuesta:
El valor de "X" es:
C.S = (-6; -5; -4; -3; -2; -1; 0; 1; 2;...∞ )
Explicación paso a paso:
-9 + 3x < 5(x + 1)
-9 + 3x < 5x + 5
-9 - 5 < 5x - 3x
-14 < 2x
-14 ÷ 2 < x
- 7 < x
comprobación:
-9 + 3.(-6) < 5( (-6) + 1 )
-9 + (-18) < 5 (-5)
-9 - 18 < -25
-27 < -25
-9 + 3.(1) < 5( (1) + 1 )
-9 + 3 < 5(2)
-6 < 10
