Awesome! Thanks. So my thinking was that I needed to divide the left side of the equation by rm when moving it left instead of subtracting and using the distributive property for multiplication. I guess since there was no coefficient for rm I wouldn't have to do that. Thanks for the help! Math has always been a challenge for me. Trying to re educate myself in older age.

All,

I am trying to understand the answer to the following equation when solving for m.

5 m - q = r m + c


I know the answer is m = (c+q)/(5-r). What I dont understand is the entire process so I know Im missing some fundamental skill here. I know you must first isolate m. So in my first step I would make the equation look like the following:


5 m - q + q = r m + c + q

=

5m = rm + c + q


Here is where I get stuck. I imagine I need to move the rm over to the left and then use distributive properties to isolate m and move the 5 and r back to the right. Im just not sure how this works out in a step by step way. Any help would be appreciated.

Thanks,

Joe
