When trying substitution, look for the variable without a number in front of it.
Substitution works well when one of the variables' coefficients is ,
as in the invisible coefficient in front of the in .
Then, you "solve" for that variable in that equation,
to get an expression for that variable in terms of the other variable:
-->
Then you substitute the expression found for the variable in the other equation.
--> --> --> --> --> --> -->
The next step is substituting for in to get
--> -->

For ,
if you try to use substitution a different way, you end up with fractions.
It is possible to do it, but I would not try it,
because I am likely to make some mistake as the calculations get complicated.
