how do I solve 3a = 9
3a=9firstly, you will need to divide each side of the equal sign by 3.3a/3=9/3Once you divide, you end up with a=3Hope this helped!
you divide 3 from both sidesand the answer is a=3because 3 divided by 3 is 0and you don't have to write itand then 9 divided by 3 is 3so replace the 9 with 3 and it gives youa=3
