Negative 2 .5 equals t over 10.
00:08
I'm going to solve this equation.
00:10
So probably the most basic way to think about it is to turn this negative 2 .5 into a mixed number or into an improper fraction.
00:18
I'm sorry.
00:19
So that's negative 5 halves, as in 2 times 2 is 4 plus the 1 is 5.
00:26
And then now i'm thinking, okay, t is being divided by 10.
00:31
So the opposite of that would be to multiply by 10, and that'll get me my variable all by itself.
00:38
Whatever we did to the left, we also have to do, i'm sorry, whatever we did to the right, we also have to do the left.
00:44
So i'll multiply by 10 over there.
00:47
And i would look at this like 2 goes into 10, 5 times.
00:51
That leaves you with 5 times negative 5 is negative 25, and that should be our answer.
01:00
Let's show this a different way and we'll kind of count it as checking our answer here.
01:07
So how about negative 2 .5 equals t over 10? that's our equation...
