Question 178556
</pre><font size=4><b>
{{{6x+3y=12z }}}--------> EQN 1
{{{(2x+y)/4=z}}}--------> EQN 2
?????? -----------------> EQN 3
.
Sorry, you need 3 EQUATIONS because you have 3 UNKNOWNS--->(x,y,z)
You can easily substitute EQN 2 in EQN 1, and that eliminates "z", but still you have 2 UNKNOWNS----> x & y.
.
Thank you,
