Answer:

see attachment

Explanation:

It usually works well to simplify the inequality as much as possible.

7(4x -1) +6x > -279 . . . . . given

28x -7 +6x > -279 . . . . . eliminate parentheses

34x > -272 . . . . . . . . . . . add 7, collect terms

x > -8 . . . . . . . . . . . . . . . divide by 34

__

This graphs as an open circle at x = -8, and shading of the number line extending to the right from there. The circle at -8 is open because -8 is not included in the solution set. However, all values greater than -8 (to the right of -8 on the number line) are included in the solution.
