Answer:

(i) [tex]x<3[/tex]

(ii) [tex]x > 2[/tex]

Step-by-step explanation:

[tex]4x - 4 < 8[/tex]

Add 4 to both sides of the equation , that is

[tex]4x - 4 + 4 < 8 + 4[/tex]

[tex]4x < 12[/tex]

divide through by 4

[tex]x<3[/tex]

Also

[tex]9x + 5 > 23[/tex]

subtract 5 from both sides , that is

[tex]9x > 18[/tex]

[tex]x > 2[/tex]
