x=3 is your answer.

To solve this equation we need to isolate the variable.

3x+6=15

So first subtract the number six from both sides. Now the equation should look like this.

3x=9

Then divide both sides by the number 3. So now the equation looks like this.

x=9/3

Simplify 9/3 to 3 and that is your answer.

x=3
