5n+6 = -4
You want to get the constants on one side.
In this case, subtract 6 from both side of the eqn.
5n+6-6 = -4-6 --> 5n = -10
Now you need n by itself, so you divide both sides by 5.
n = -10/5 and simplify n = -2
Plug n back into original eqn:
5(-2)+6 ?= -4 and the answer is yes, so n =-2 is the correct answer

5n+6=-4
5n+6+=-4
-4 -4
5n+2=0
5*2=10

5n+6=-4
___4 __4 (add 4 to both sides)
5n+10=0
5n=-10
n=-2
-10 = -10
