Answer:
n = 4
im not good at explaining by text but i hope this helps
Step-by-step explanation:
3n - 8 = 4
you want the variable by itself so you will start with the number without the variable
3n - 8 = 4
next to the 8 is a - sign so it will is negative now it has to be the opposite
3n - 8 = 4
+8. +8
you cancel out the 8 and 4+8 is 12
now you have to do 12 ÷ 3 to get the variable by itself
12 ÷3 is 4
