7m = 9(m + 4)
Use Distributive Property
7m = 9m + 36
Subtract 9m From Both Sides
-2m = 36
Divide by -2 On Both Sides
m = -18

7m=9m+36 (you distribute the 9 to the m and the 4)
0=2m+36 (subtract 7m from both sides)
-36=2m (subtract 36 from both sides)
m= -18 (divide both sides by 2)

7m = 9(m + 4)
or 7m = 9m + 36
or 7m -- 9m = 36
or -- 2m = 36
or m = 36 / (--2)
or m = -- 18

7m = 9(m + 4)
7m = 9*m + 9*4
7m = 9m + 36
7m -9m = 9m -9m + 36
-2m = 36
-2m / -2 = 36 / -2
m = -18

OK
Key is to expand, combine, and isolate the variable
7m=9(m+4) ; expand
7m = 9m + 36 ; combine m's by subtract 9m from both sides
-2m = 36 ; isolate m by dividing by -2
m = -18
Hope that helps.
