12t=-132

Aug 25th, 2015

Thank you for the opportunity to help you with your question!

We have the algebraic equation 12t = -132. Our goal is to solve for t. 

To get t by itself, we must divide both sides by 12. This will give us 12t/12 = -132/12, which reduces down to t=-11.

So t=-11.

If you want to check the answer, you can plug it back in: 12*-11 = -132. 

Please let me know if you need any clarification. I'm always happy to answer your questions.

18+z=40

So if you need to get z by itself, how do you think you should go about doing that?

Aug 25th, 2015

divide by 18

subtract by 18

If our equation is 18+z=40 we wouldn't divide by 18. We have to get rid of 18 on one side and put it on the other. What can we do to make 18 on the left hand side go away? 

If we divide by 18 on both sides, then that turns into 18+z/18 = 40/18 which turns into 1+z/18 = 20/9.

Right we subtract by 18. The what will z be?

I'm counfused

Z=22 right ?

Aug 25th, 2015

Sorry I replied and then saw you commented again. So to check our answer we can plug it back in to find 22+18=40. So yes, z=22.
