Well, the right side of your equation is equal to ' 1 ', so that's the way we'll write it from now on.
We can't tell whether the left side of the equation is (9/2)t or 9/(2t) . Here are both solutions.
-- If the left side is (9/2)t, then the equation is
(9/2) t = 1
Multiply each side by 2 :
9 t = 2
Divide each side by 9 :
t = 2/9
= = = = = = = = = = = = = = =
-- If the left side of your equation is 9/(2t) , then the equation is
9 / (2t) = 1
Multiply each side by 2t :
9 = 2t
Divide each side by 2 :
t = 9/2
