Arhenius equation solving for K1/T2

[lazybone]

Hey guys its my first time in this forum and I need help with my chemistry. I guess its kind if basic chem. Basically its a question to solve for K2 or T2. Like I'm not sure how to isolate the k or T.

Homework Statement

Homework Equations

ln(K1/K2)=Ea/R(1/T1)-(1/T2)

Ln(23/x)=139J/8.314J(1/750)-(1/800)

The Attempt at a Solution

I keep getting a different answer than the real one . My professor said it is 6.07. Please help I'm not sure how to isolate the K2. And what happens if I need to find T2. Thanks

Use simple Algebra to solve this. Show some work on how you tried to isolate it, and I will then guide you on how to figure it out.
