Question

What is the solutionfor this equation? 5x +9=2.5 I really need to make sure I did this right

Answer 1

Answer:

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!

Answer 2

Answer:

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
