I have two set of equations, one in the form,

eq1 = ({0.15, 0.85, X1} == {X3, X2 + X4, X5})

and the other in the form

eq2={1. X1 == 9/5, X4/(X3 + X4 + X5)==1/3}

Solve understands both Solve[eq1] and Solve[eq2] but if I want to solve the two sets simultaneously, what is the best way to combine eq1 and eq2 into a single list of equations, either of the form of eq1 or of eq2, that Solve can understand?
