You can put this solution on YOUR website! Using order of operations, we expand the equation to , which simplifies to . Adding 6 to both sides produces , which simplifies to . Now subtract from both sides: , which simplifies to . To check it, substitute 9 in for x in the original equation: , which simplifies to and that further reduces to , and finally , which is a true statement. Because that is a true statement, that means our answer of is correct.
