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?

OpenStudy (anonymous):

no i think

mathslover (mathslover):

What is (28-28) ?

OpenStudy (anonymous):

0

mathslover (mathslover):

Good. What is 28-22.4?

OpenStudy (anonymous):

5.6

mathslover (mathslover):

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

mathslover (mathslover):

"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
