So what you want is to find out what n's value is. To do that, you'll have to have n on ONE SIDE of the equation. Let's start by moving -40 to the opposite side (remember to flip the signs), making it 4n=-14n+14+40. Now, combine like terms. 14+40= 54. Now you have 4n=-14n+54. Let's go ahead and move -14n to the other side to have n in one side of the equation as mentioned before... leaving us with 14n+4n=-26. Combine like terms again. 14n+4n= 18n. Now we have 18n= 54. To get the final result, we need to have n by itself, meaning get rid of the 18 infront of it. Because they're one term, we have to divide it by 18 to have n by itself and also divide 54 by 18. Remember what you do to one side with multiplication or division, you do to the other. 54/18 = 3. Therefore, n = 3.
