The correct answer is A

EXPLANATION

We have

[tex]-4x<28[/tex].

We want to solve for x so we divide through by

[tex]-4[/tex]

and reverse the sign of the inequality.

[tex]\frac{-4x}{-4}>\frac{28}{-4}[/tex]


This gives us,

[tex]x>\frac{7 \times4}{-4}[/tex]



[tex]x>\frac{7}{-1}[/tex]



[tex]x>-7[/tex]
