State all integer values of x in the interval –2 < x < 5 that satisfy the following
inequality:
5x + 9 < 7

Respuesta :

Solve second one

[tex]\\ \sf\longmapsto 5x+9<7[/tex]

[tex]\\ \sf\longmapsto 5x<7-9=-2[/tex]

[tex]\\ \sf\longmapsto x<\dfrac{-2}{5}[/tex]

[tex]\\ \sf\longmapsto x<-0.4[/tex]

Then

-2<x<7

  • x={-1,-2}
