    x = - 1.3

    Step-by-step explanation:

    5x + 9=2.5

    subtract 9 from both sides

    5x = - 6.6

    divide both sides by 5

    x=-1.3

    The answer is - 1.3.

    Step-by-step explanation:

    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!
