Solve for the variable
3n-8=4

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
