Question 262647: If twice a number is subtracted from 8, the difference is 12. What is the number?
My attempt was:
2x-8=12 but then I realized I wasn't subtracting from 8 I was subtracting 8 from 2x. Answer by unlockmath(1688) (Show Source):
You can put this solution on YOUR website! Hello,
Yes, you were close. So we set it up like this:
8-2x=12 Now subtract 8 from both sides to give us:
-2x=4 Divide both sides by -2 to get:
x=-2
So let's see if this works.
8-2(-2)=12 I'll let you figure it out from here.
Make sense?
