Transposing Equations

Fromvert

Having trouble to transpose the below equation. It would be of great help if someone could transpose it for me showing each step.

Q. Solve the following equation for m:

0.0081 = 0.0092 - [2.1/(m x 2450)]

Any help is much appreciated.

Here's my shot at it:

0.0081 = 0.0092 - [2.1/(m x 2450)]

2.1 / (m x 2450) = 0.0092 - 0.0081

2.1 / (m x 2450) = 0.0011

2.1 / 2450 / 0 .0011 = m

0.77922 = m

Thanks Rigal, thats answer I had but just didnt know how I got it. Your a star.

Could anyone help with this:
Solve for gc

0.9 = (0.012-0.008)/(0.012 - gc)

0.9 (0.012 - gc) = 0.012 -0.008 = 0.004

0.012 - gc = 0.004/0.9 = 0.0044

-gc = 0.0044 - 0.012

gc = 0.012 - 0.0044

gc = 0.0076

.9 = (0.012-0.008)/(.012-gc)
.9(.012-gc) = 4x10^-3
.0108-.9gc = 4x10^-3
-.9gc = -6.8x10^-3
gc = 7.556x10-3 = 0.0076

Edit: timbrophy got in there first:pac:
