Lets expand both multiplications first.
Simplify down the right side.
Add 38.25 to both sides.
Subtract 11.22x from both sides.
Divide by -21.42 on both sides. Because we're dividing by a negative, we need to change the inequality direction.
This means, out of the options available, (-2.5, ∞) is the correct answer.
