put all the 'm's on one side.
mathslover (mathslover):
You have 9.1 m -28 = 6.3m -22.4
Add 28 both sides.
mathslover (mathslover):
9.1m - 28 + 28 = 6.3 m - 22.4 +28
mathslover (mathslover):
or write it as : 9.1m + (28-28) = 6.3 m + (28-22.4)
Can you simplify it further?

Good.
So you get now :
\(9.3m + (28-28) = 6.3 m + (28-22.4) \implies 9.3 m + \bf{0} = 6.3m + \bf{5.6}\)
mathslover (mathslover):
That is : 9.3m = 6.3m + 5.6
Now subtract both sides by 6.3 m
=> 9.3 m - 6.3 m = 6.3 m - 6.3 m + 5.6
=> 9.3 m - 6.3 m = 0 + 5.6
=> 9.3 m - 6.3 m = 5.6
mathslover (mathslover):
Can you tell me what is 9.3 m - 6.3 m ?
OpenStudy (anonymous):
3
mathslover (mathslover):
No! 9.3 m - 6.3 m = m(9.3 - 6.3 ) = 3m

"m" is the variable there. So it will not go anywhere.
That is 3m = 5.6
Divide both sides by 3 now.
3m/3 = 5.6/3
m = 5.6/3
OpenStudy (anonymous):
divide that?
mathslover (mathslover):
yes
