Answer:

  • B. when a is negative

Explanation:

Inequality given:

  • ax + b > c

When solving we do steps:

  • ax > c - b
  • x > (c - b)/a

At the second step both sides divided by a.

When a is positive the inequality symbol remains as is, when a is negative we have to divide both sides by -1 as well. This will reverse the inequality symbol.

Correct answer choice is B.
