850-53x m= 720-39x m
insens350 [35]

Answer:

9.286

Step-by-step explanation:

I'm not guaranteeing this answer. If this is correctly written without any indication of how to deal with x, then here is as much as you can do.

850-53x m= 720-39x m                         Subtract 720 from both sides.

850 - 720 - 53x = 720 - 720 - 39xm      Combine

- 53xm + 130 = - 39xm                             Add 53x

-53x+53xm + 130 = -39x + 53xm            Combine

                      130 = 14xm                         Divide by 14

xm = 130/14

xm = 9.28

===============================

You can use the same steps above. I'm abbreviating the steps because they are the same.

I'm sure there is more to the problem, but I can't imagine what it is. If you have additional directions, put it under this answer. I will get it as a comment.

850-53m= 720-39m

850 - 720 - 53m = - 39m

130 - 53m = - 39m

130 = -39m + 53m

130 = 14m

130/14 = m

m =9.286
