How do you solve -3x-4>5

Answer 1

x < -3

Explanation:

We must isolate x.

Start by adding 4 to both sides, obtaining -3x > 9.

Next, divide both sides by -3, remembering to reverse the direction of the > symbol:

-3x 9

------ > ----- ↔ x < 9/(-3), or x < -3

-3 -3

Answer 2

x<−3

Explanation:

−3x−4>5

Step 1: Add 4 to both sides.

−3x−4+4>5+4

−3x>9

Step 2: Divide both sides by -3.

−3x
