It is probably very well explained in a basic math book which you either
own or can borrow at many libraries.
The method is called substitution and you most probably dont get much
help or insight from R.
If it is a linear equation system with more unknowns use the function
'solve' which you would have found by typing help.search("solve
system")
in R.
Question to R help.search experts:
Why doesn't help.search("solve Equations") find solve ?
