Theres this chemistry problem im getting stuck in because i'm confusing myself with the math.
Equation given = %O2 saturation = 100 x (pO2/(pO2 + K)
%O2 = 35
K = 1.51
how do I calculate pO2?? I can't seem to cancel them out correctly.
Answer = 0.813

35=(100*x)/(x+1.51)
35x+35*1.51=100x
65x=52.85
solve for x 
Ahh I can't believe I didn't see that! I appreciate your help!
