The answer would be 12. What you do is line it up like this, 7x-16=x+8. Then you will subtract x on both sides and get, 6x-16=8. Then you will add 16 on both sides of the equal sign and get,6x=24. then you will divide 6 on both sides of the equal sign and get x=4. The you will take for and replace your x and put 4. So you will have 7(4)-16=? And your answer will be 12.
