Example of what is going on:

jimthompson5910 (jim_thompson5910):

you wrote "inequalities" but placed an equal sign so it's really an equation

jimthompson5910 (jim_thompson5910):

which variable are you trying to solve for?

jimthompson5910 (jim_thompson5910):

also, in your example, there's an error: the m - M should be m + M

OpenStudy (anonymous):

Solve for m on the one I am trying to do

OpenStudy (anonymous):

yeah for whatever reason I keep writing inequalities instead of equations.,. I

jimthompson5910 (jim_thompson5910):

First multiply both sides by F. Then divide both sides by 'a' to isolate m. \[\Large k = \frac{ma}{F}\] \[\Large kF = ma\] \[\Large ma = kF\] \[\Large m = \frac{kF}{a}\]
