Answer 1

Medal and fan to best answer :D

Answer 2

depends. Elimination, substitution, subtraction, addition, division, multiplication...

Answer 3

when at least one of the variables has the same coefficients in both equations
or is an simple multiple of the same variable in the other equation, then elimination is a good strategy.

When one of the variables can be easily isolated into a simple expression, then substitution is a good strategy.
