Does x = 36 work?  Check it!

(1/4)x = 9 put x = 36 in... (1/4)*36 = 9 which gives 36/4 = 9 Yep!

Here's the way you do NOT want to do this guy!  (And do NOT let me catch you doing it!)

(1/4)x = 9

Do NOT divide both sides by 1/4!

(1/4)x / (1/4) = 9 / (1/4) Because you'll probably mess this thing up... especially, if I take your calculator away!

TRY IT (the right way):

Solve          (1/3)x = 8          *And check it!
