Answer:

x < 0

Explanation:

We are given this inequality:

3x + 4 < 4

And we want to solve it.

Solving inequalities is very similar to solving equations. We want to isolate the variable (in this case, x) on one side, while leaving the numbers on the other side.

To start, we can subtract 4 from both sides.

3x + 4 < 4

-4 -4

__________________

3x < 0

Now, we have the numbers on one side and the variable on the other, but we aren't done yet, as we want to solve for the value of x, or 1x, not the value of 3x.

So, we'll need to divide both sides by 3.

3x < 0

÷3 ÷3

___________

x < 0

The answer is x < 0.
