What sort of formula would you use to answer a question like 7-t equals 3 plus 7t to find T?
Sirlongshanks
Simply set the two equal.
7 - t = 3 + 7t
So, if you add t to both sides of the equation and subtract 3 from both sides of the equation, you get:
4 = 8t
So then, if you divide by 8 on both sides of the equation, you get:
t = 4/8 = 1/2
Hope this helps :)
