vocaloid · Answer

add 9 to both sides first, and then tell me what you get

anonymous · Answer

wait wht

vocaloid · Answer

left side is 5x - 9
right side is 36

add 9 to the left side, add 9 to the right side, and then tell me what you get

jadeishere · Answer

You 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 >.<

I had got 14 and 45

jadeishere · Answer

Okay, 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

anonymous · Answer

$$5z-9=36\5z=36+9\5z=45\z=\frac{ 45 }{ 9 }\z=5\ ans$$

jadeishere · Answer

Um, wrong @enione

anonymous · Answer

Just plug in the numbers to z and see if it equals to the answer

jadeishere · Answer

$45/5 = 9$

anonymous · Answer

oh! no,  $$z= 36\div 5\z=9 Ans$$
