How do you write a system of linear equations in two variables? Explain this in words and by using mathematical notation in an equation.

Steve,
You need to have two ways the variables are related. Take a look at some of the coin problems, mixture problems, tickets sold problems, etc. Do a search in the box at the top right and I'm sure you will see how they are done.
For example, if you have 7 coins (dimes and quarters) which add up to $1.15, then
d+q = 7
10d+25q = 115
