Sure it can. If a single linear equation has two variables, then it defines not one solution, but many solutions. If you plot the solutions on a graph, where one axis is one variable and another axis is another variable, you get a straight LINE. That's why the equation is called LINEar.
Example of a linear equation with two variables: y-x=3. Its graph: graph%28+300%2C+200%2C+-5%2C+5%2C+-5%2C+5%2C+x-3%29+

Yes a linear equation can have 2 variables and the reason it can is because of x and y. ya see?
