Answer: T = tw
Explanation:
it's basically solve for
you cross the bridge and say:
2T = 6 - 5 + three
the signs when you cross
2T = four
then you divide by the co-efficient (i.e 2)
T = two
it's not showing values.... first missing space is three then it's four then it's two. I wrote the numbers in words cos it's not showing as numbers.
