of the given equation take lcm and then divide both the equations to get
n(Py+Qx)=m(Px+Qy)
take all y terms on one side and all x on one side to get
x(mP-nQ)=y(nP-mQ)
from here
x/y= (nP-mQ)/(mp-nQ)
n(Py+Qx)=m(Px+Qy)
take all y terms on one side and all x on one side to get
x(mP-nQ)=y(nP-mQ)
from here
x/y= (nP-mQ)/(mp-nQ)
