[D]: " x > -3 " .
Explanation:
Given the following inequality:
7x + 18 > - 3 ;
Simplify to solve for "x" :
7x + 18 > -3 ;
→ Subtract "18" from EACH SIDE of the inequality ;
7x + 18 − 18 > - 3 − 18 ;
to get:
7x > -21 ;
Divide each side by "7" ; to isolate "x" on one side of the question; and to solve for "x" ;
7x / 7 > -21 / 7 ;
to get: x > -3 ; which is: Answer choice: [D].
