Question

Solve for x: −2x − 4 > 8

Answer 1

-2x -4 > 8 Move the -4 to the other side and use the opposite operation -2x > 8+4 Add 8 and 4 -2x > 12 Divide -2 from both sides x = -6

Answer 2

-2x-4 > 8
-2x > 12
x < -6

Wait, what? Why did I reverse the direction of the greater than sign to a less than sign? Well, when you divide a negative number in an inequality problem, you need to reverse the sign. I hope the actual solving is obvious. If it's not, just ask for clarification!
