Prove reversible adiabatic pvγ = constant 22 solved problem

The following is the equation which connects u, p and v for several gases u = a + bpv where a and b are constant. Prove that for a reversible adiabatic process, pv^γ = constant, where γ = ^{(b + 1)}/_b.

The following is the equation which connects u, p and v for several gases

u = a + bpv
