This question confuses me, I need to correct the error. I just need number 30.

Explanation:
For 29. [tex]x \geq -12[/tex]
[tex]\frac{x}{4} + 6 \geq 3[/tex]
x + 24 [tex]\geq 12[/tex]
x [tex]\geq -12[/tex]
For 30. -2(1 - x)[tex]\leq 2x - 7[/tex]
-2 + 2x [tex]\leq 2x - 7[/tex]
-2 [tex]\leq -7[/tex] --> undifiend because -2 [tex]\neq -7[/tex]
