t=75/56

Explanation:

Add 5/7 to both sides

t = 5/8 + 5/7

You have -5/7 + 5/7 = 0 on the left side; 5/8 + 5/7 requires finding of common denominators.

35/56 + 40/56 = 75/56

So

t = 75/56

t = 9 3/8

Explanation:

In the absence of any formatting or parentheses, I wonder if you meant the question to be as follows? It is solved below, just in case.

(t-5)/7 =5/8

There is only one fraction on each side of the equation, so you can cross-multiply

8(t-5) = 7xx5

8t-40 = 35" "larr add 40 to both sides

8t = 35+40

8t =75" "larr divide both sides by 8

t = 75/8

t = 9 3/8
