Answer:
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: [tex]\frac{3x}{3} = \frac{12}{3}[/tex]
Now, we actually divide both sides now, which should look like this: [tex]x = 4[/tex]
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!
its pretty east you just divde both sides by 3 to get the value of x, so since its 3x you divide it by 3 and you also do that with the other side so 12/3=4 so x=4
