Haha, you first start off with adding 3 to both sides, cancelling the -3, and adding it to 9. you end up with 5x=12, in which you divide both sides by 5. you get 2 and 2/5 or 12/5! hope that helps :)
Answer: First, you would need identify what needs to be moved in order for the coefficient (5) and the variable x to be alone on one side of the equal sign.You'll see that -3 must be moved across the equal sign,resulting in 5x standing alone on one side. -3 has to be canceled out so you +3 to make it zero and +3 on the opposite side of the equal sign. The equation would now be 5x=12 because 9+3 is equivalent to 12.Now you perform division, dividing both sides by 5 for the x(variable) to stand alone. The answer is x= twelve-fifths(12/5).Then you will obviously you plug it back in to ensure of a correct answer.
