title: How to Solve Equations with java?
body: <p>I have three equations like the following ones:</p>
  
  <ul>
  <li>x + y + z = 100;</li>
  <li>x + y - z = 50;</li>
  <li>x - y - z = 10;</li>
  </ul>
  
  <p>How can I find the values of x, y, and z with Java?</p>
  
  <pre><code>String equation1="x+y+z=100;";
  String equation2="x+y-z=50;";
  String equation3="x-y-z=10;";
  
  int[] SolveEquations(equation1,equation2,equation3) {
     // to do
     // how to do?    
  } 
  </code></pre>
  
  <p>Do you have any possible solutions or other common frameworks?</p>
