[tex]\eta = 1 - \frac{Q_c}{Q_h}[/tex]

I have everything except Qh,

i stuck the equation into my graphics calculator and get 13039

n = 0.27
Qc = 9519 J

how'd i solve for Qh using that equation?
cheers

[tex]\eta Q_h = Q_h - Q_c[/tex]

[tex]Q_h(1-\eta)=Q_c[/tex]

[tex]Q_h=\frac{Q_c}{1-\eta}[/tex]
