The problems were reduced to systems of linear equations, that were solved then by different solution methods (Substitution, Elimination).


So, these solutions are representative and helpful, and you may use ANY of them as your TEMPLATE.


Read them attentively, and then solve your problem by the same way.



Notice that this forum has a HUGE archive of problems solved earlier.

It is your unlimited source of potential TEMPLATES.

Simply print the key words followed by the word "algebra.com" and look in GOOGLE what will happen.

It may happen, that your problem is just in the archive and wait patiently when you get / (you find) it.
