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
