Question 100737
x+2x+5=x+19
Just think of the "x" as "car"
-----------------
You have 
car + 2 cars + 5 = car + 19
-----------
Substract a car from both sides to get 
2cars + 5 = 19
Subtract 5 from both sides to get:
2cars = 14
Divide both sides by 2 to get:
car = 7
----------------
the same procedure would get you x = 7
