Solve the system of linear equations and check any solutions algebraically. (If there is no solution, enter NO SOLUTION. If the system is dependent, express x, y, and z in terms of the parameter a.)

3x-3y+6z=6
x+2y-z=8
5x-8y+13z=4

I don't know what parameter A is...

Do I solve for x, y, or z? What is parameter a?

I got the answer (6-a,a,a-2)! Thanks for those who clicked on my questioning with helpful intentions.
