Subject: System of equations

I am having difficulty teaching word problems with a system of equations
to my students. I don't think I was ever taught a process for solving them
and I can't come up with one. I would appreciate any and all help. I have
included an example problem below. Thank you.

A paper manufacturer has two factories. One factory produces 800 reams of
medium grade paper and 300 reams of high grade paper per day. The second
factory produces 200 reams of medium grade paper and 700 reams of high
grade paper per day. A publishing company has placed an order for 1700
reams of medium grade paper and 2200 reams fo high grade paper. If both
factories work together to fill this order, how many days should each
work on the order? Let x = the number of days for the first factory to
work on the order. Let y = the number of days for the second factory to
work on the order.
a) Write the two equations
b) Solve the system of equaions
