Question 1196577
<pre>
You should include a question.  The assumption is you want to solve the system for x and y:

2(3x + 5x = 54) --> 6x + 10x = 108
                  -(6x +  4y =  72)
                  ------------------
                          6y =  36  -->  {{{ highlight(y = 6) }}}  --> {{{ highlight(x = 8) }}}
