Answer: Solving for x

Step-by-step explanation:

First add the known variables. This gets you 3.2

Next, since you know that multiplication is used to find 6.4 we take the inverse. 6.4/3.2

To get 2.

And finally, check you work.Fill in the x value and substitute for x. .9(2) + 2.3(2) to make sure your division is correct.

Hope this helps!!
