Not all systems of linear equations have a solution. Give an example of a system of linear equations that has no ordered pair satisfying it. Explain your answer.

Systems of linear equations that graph parallel lines have no solution. They are called inconsistent systems.
Example:
$\displaystyle x+y=5$
$\displaystyle 2x+2y=7$
Same slopes. Different y-intercepts. Parallel lines.

Here's my hint:
We don't have a solution to a linear system of equations if there are two lines that are parallel...
Can you try to come up with a system of equations now?
