HELLO THERE

THE ANSWER IS

Step 1: Subtract 3n from both sides.

12n-5-3n=3n+8-3n

9n-5=8

Step 2: Add 5 to both sides.

9n-5+5=8+5

9n=13

Step 3: Divide both sides by 9.

9n/9 =13/9

therefore the answer is

n=13/9

hope this helps

thank you

12n - 5 = 3n + 8

12n = 3n + 8 + 5

12n = 3n + 13

12n - 3n = 13

9n = 13

n = 13/9 or 1.44

hope this helped! :)
