Question

Solve the inequality for x.

4 − 4x < 16

x < −3
x > −3
x > 3
x < 3

Answer 1

x > -3

Explanation:

4 - 4x < 16

- 4x < 16 - 4

- 4x < 12 (note that both can be divided by -4)

x > -3

That's the final answer.

AND if you're co fused about why the sign changed, you should always remember this

• ALWAYS change the inequality sign when you divide (÷) or multiply (×) by a negative number

By negative num I mean any number that starts with a minus for example -2, -3, -5, -100
