First: You need to isolate the number with the variable (such as x). In this case, you subtract 9 from one side, so brush your teeth and subtract 9 from the other side. If you do the math, you end up with a -6.5.
Next: You need to isolate the variable itself. In this case, you need to divide by 5 to get x itself, so divide by 5 on the other side. You get -1.3 because a negative times or divided by a positive equals a negative.
Lastly: BOOM! You got your answer! Congrats! You've just gotten smarter!
