Best ResponseYou've already chosen the best response.1You need to isolate the variable, in order to do that, you take 9 away from each sides, so to make 0 you add 9 + 9, then add 9 to the right side of the equation because whatever you do to one side, you do to the other >.<

Best ResponseYou've already chosen the best response.1Okay, so when you add 9 to 36, you get 45 so now you have 5z = 45 in order to COMPLETELY isolate the variable you need to divide both sides by 5 because of \(5\) (z) so now you have z = 45/5

Best ResponseYou've already chosen the best response.0\[5z9=36\\5z=36+9\\5z=45\\z=\frac{ 45 }{ 9 }\\z=5\ ans\]
