First add 35 to both sides. Second subtract 2m from both sides. Lastly divide both sides by 5.

Isolate m using inverse operations, get m by itself. (addition and subtraction, mult. and div.)

7m-35=5+2m\ (subtract\ 2m) \\ 5m-35=5\ (add\ 35) \\ 5m = 40\ (divide\ by\ 40) \\ \boxed{m=8}

You have to get "X" by itself so you subtract 12, 7-12 is -5 so "X" = - 5
