You can put this solution on YOUR website!
substitution, elimination or cramers rule which is easiest
---------
Try not to dispair. Anyone of these methods will get you
the answer. Cramer is easy if you have a calculator and
know how to use it. Substitution is a bit messy if the
equations are complicated. Elimination is messy if the
coefficients of x and y are big numbers or decimals or
fractions.
---------------
Try to look at material which is going to be presented
before it is presented. That way you will have some
small understanding to build on. Try also to hook up
with someone who understands the math---a fellow student
or worker or tutor to resolve your difficulty.
