  <p>How would you solve a linear Equation with multiple variables in the web? maybe using Gaussian elimination or ... ? Is it possible with php and recommendable?</p>
  
  <pre><code>1500 + 100 w                 = 10,000 s
  3000 + 1000 s                = 3000 w
  5000 + 2000 s + 100 w + 30 r = 150 r
  
  =&gt;   s = 0,16 | w = 1,05 | r = 45,21
  </code></pre>
