title: solving equations and using values obtained in other calculations - SAGE
body: <p>the function solve() in SAGE returns symbolic values for the variables i solve the equations for. for e.g:</p>
  
  <pre><code>sage: s=solve(eqn,y)
  sage: s
  [y == -1/2*(sqrt(-596*x^8 - 168*x^7 - 67*x^6 + 240*x^5 + 144*x^4 - 60*x - 4) + 8*x^4 + 11*x^3 + 12*x^2)/(15*x + 1), y == 1/2*(sqrt(-596*x^8 - 168*x^7 - 67*x^6 + 240*x^5 + 144*x^4 - 60*x - 4) - 8*x^4 - 11*x^3 - 12*x^2)/(15*x + 1)]
  </code></pre>
  
  <p>My problem is that i need to use the values obtained for y in other calculations, but I cannot assign these values to any other variable. Could someone please help me with this?</p>
