4x2 - 33x = 27

OpenStudy (thesecret20111):

If you want to solve for x you need to first simplify the equation by working out all that you can.

OpenStudy (thesecret20111):

So 4*2 we know = 8 Therefore we input this into the equation. So the new equation is 8-32x=27

OpenStudy (thesecret20111):

Now take the 8 from both sides. That gives us -32x=27-8

OpenStudy (thesecret20111):

Therefore -32x=19

OpenStudy (thesecret20111):

Now we divide both sides by -32 to get x by itself. That means we have x=19/-32

OpenStudy (thesecret20111):

x=-0.59

OpenStudy (thesecret20111):

Now thats a rather non-rounded answer so I may have miss read your question. But if the question was indeed 4*2-33x = 27 then the answer is x=-5.9
