16=3x%2B6x%2B7

Step 1. Combine like terms (x-terms in this case)

16=%283%2B6%29x%2B7

16=9x%2B7

Step 2. Subtract 7 from both sides of the equation

16-7=9x%2B7-7

9=9x

Step 3. Divide by 9 to both sides of the equation

9%2F9=9x%2F9

x=1

Step 4. ANSWER: The solution is x=1.

I hope the above steps were helpful.
