So basically what you’re trying to do is isolating the variable (in this case it’s “m”). First you should simply, in this case you would do distributive property on the left side. Then you would take all the variables to one side, by either subtracting them or adding them (subtract the smallest variable from its own side, then do the same thing on the other side). Then take the constants and put them both on one side (in this case i’m subtracting the five from both sides). Then isolate the variable by dividing the coefficient by everything.
