m+3n = 7 solve for m
Note, Anonymous.....
m = -3n + 7 is the same thing as m = 7 - 3n ......
This means that we want the thing we are "solving for" on one side of the equation and everything else on the other....so we have
m+3n = 7 subtract 3n from both sides
m = 7 - 3n
And that's it !!!
M=-3N+7
If i am correct, CPhill has forgotten the negative 3.
