The solution of the inequality is -9 >= x9x.

Explanation:

Solve the inequality by using inverse operations to isolate xx.

-7 >= 2 + x72+x
-7 - 2 >= 2 - 2 + x7222+x
-9 >= x9x

If this is part of an assignment covering Linear Inequalities in One Variable, it will be graphed on a number line. There will be a closed dot at -99, and the number line would be shaded to the left of -99. However if this is part of an assignment covering Linear Inequalities in Two Variables, it is graphed on a coordinate plane as shown below.
