Lets say you have 5 apples, but the you give away 3 of them.
To work how many you have left you take away.
5-3 = 2
Lets apply this with fractions now.
You have 9/7 yard, but then you give away 7/20 yard.
Now you take them away:
9/7 minus 7/20 = 131/140
Hope this helps :)

-2 x 2 = -4
Simplified is 6^-4
Answer:
t=5/3
Step-by-step explanation:
in order to get our answer, we have to first open it up which comes to 3t-6=-1
next,we have to isolate the variable, so we add (6) to (-1)
then we get 3t=5
so, t=5/3
