Let λ,μ∈R\lambda, \mu \in \mathbf{R}λ,μ∈R. If the system of equations 3x+5y+λz=37x+11y−9z=297x+155y−189z=μ\begin{aligned} & 3 x+5 y+\lambda z=3 \\ & 7 x+11 y-9 z=2 \\ & 97 x+155 y-189 z=\mu \end{aligned}​3x+5y+λz=37x+11y−9z=297x+155y−189z=μ​ has infinitely many solutions, then μ+2λ\mu+2 \lambdaμ+2λ is equal to :
