Solve: 3x=12

1. 36
2. 4
3. 5
4. 3

The answer is 4.

Step-by-step explanation:

This is a basic one-step algebra problem.

We have: 3x = 12.

We would like find what x equals. In order to do that, we must have the x variable on one side of the equals sign, and the rest of the numbers on the other side. In other words, we have to isolate the x variable away from its coefficient.

To do this, we must divide BOTH sides of the equation by 3. This would mean that the 3 on the left side of the equals sign cancels out, totally getting rid of the 3.

Here's what it should look like:

Now, we actually divide both sides now, which should look like this:

This is because 3 divided by 3 is 1, and 12 divided by 3 is 4.

Hence, our solution for x is 4. Hope this helped!

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!
