Question

How do you solve the inequality `z/4+ 7> -5`?

Answer 1

Solve assuming it it is a linear equation. In the case of a negative multiplication/division over the inequality sign, switch the direction of the inequality sign.

Explanation:

`z / 4` + 7 > -5

`z / 4` > -12

z > -12 • 4

z > -48

If you select a test point, say -44, it should work in both the original equation and in the final result.
