GalinKa [24]

Answer:

N= -8

Step-by-step explanation:

you will add 10and 6 to get 16

then add 8 to each side to cancel out. 16+8 will give you 24. now subtract the 8 off of in onto 5n

5-8 will give you -3. Now you need to divide -3 off of N on both sides so it cancels. -3÷-3=N....24÷-3=-8. Giving you N=-8
