Question

Can someone explain how to do this?
4x+6<-6

Answer 1

x < -3.

Explanation:

The rules are similar to solving an equation:

4x + 6 < -6

Subtract 6 from both sides:

4x + 6 - 6 < -6 - 6

4x < -12

Divide both sides by 4

x < -3.

The only exception to the rules is that if you are dividing both sides by a negative value the inequality is flipped.

Answer 2

The answer to your question is:

Explanation:

Your problem is an inequality which has a lot of possible solutions. To solve it,

just find the value of x and express the result as an interval.

4x + 6 < -6

4x < - 6 - 6

4x < - 12

x < - 12 / 4

x < - 3

The solution means that this inequality is valid for of the numbers lower than -3. It is express like

( - ∞ , -3)

-3 is not included in the solution.
