What is the answer of 3x=12?

Answer: Four

Step-by-step explanation:

Since it's a one step equation, and you have to do it do the opposite operation to get x by itself. So, since 3 is being multiplied by x, you have to divide it to get it by itself to find the missing value. What you do on one side you have to do on the other, so you divide 3 by 12 which equal 4. So, x equals 4.

3x=12

Divide by 3 for 3x to find x. Also divide by 3 for 12

3x/3=12/3

Cross out 3 and 3, then divide by 3. Equals to x.

x=4

Answer: 4
