What inequality will you get when you multiply both sides of the inequality x > 7 with -2?
Step 1 of 2

Answer 1

-2x < -14

Explanation:

In this problem we are multiplying both sides with the number "-2". Let's solve that first:

1. (-2)x > 7 → 2x > 7

The x is not defined, so we simply get -2x.

2. -2x > 7(-2)

7 x -2 would equal 14.

However, there is one extra rule with inequalities. Anytime you mutiply or divide both sides of the each, you must flip the sign.

-2x > -14 → -2x < -14

Hoped this helped! :D
