Hi I was hoping that you could help me with this problem. I believe that this is a high school level problem but as an adult who has forgotten the "rules", I am stuck. the equation is this: x=t2/(t1t2) we know that x=5.73 t1=303 we must solve for t2 Thank you Anthony 

Hi Anthony, An equation is like a balance. You can can change one side by adding, subtracting, multiplying or dividing a quantity as long as you perform the identical operation on the other side also. The goal is to obtain an equivalent equation of the form
In your equation
I would first multiply both sides by t1t2 to get
so
Expanding the left side gives
You want one side of the equation to have only t2 so add x t2 to both sides to get
which simplifies to
Now divide both sides by (1 + x) to obtain
You have x = 5.73 and t1 = 303 so
