[sage-support] Super newbie question re: solving systems of equations

2017-09-21 Thread Natalie Ulrich
I'm using SageMathCell to solve chemical equilibrium problems, so at least one set of my solutions has to be real and positive. Here's my code: var('x, y, z') xi=0 yi=0.150/2.0 zi=0.150/2.0 K=8.3e-4 eq1=K == y*z/ x eq2=xi+yi==x+y eq3=2*xi+2*zi==2*x+2*z solve([eq1, eq2, eq3],[x, y, z])
