Bonsoir,
Je n'arrive pas à faire passer la formule :
hxPs = (h-Ss)xPe + SsxPa
à :
Ss = hx(Ps-Pe)/(Pa-Pe)

je suppose que x = multiplier
je remplace par *
h*Ps - (h-Ss)*Pe - Ss*Pa =0
h*Ps - h*Pe + Ss*Pe - Ss*Pa =0
Ss (Pe -Pa) + h ( Ps - Pe )=0
=> - Ss (Pe -Pa) = h ( Ps - Pe )
Ss ( - Pe +Pa) = h ( Ps - Pe )
Ss ( Pa - Pe) = h ( Ps - Pe )
Ss = h ( Ps - Pe ) / (Pa -Pe)
