How do I do this,

Point A(3,0,-2) lies on the line r=3i-2k+ t(2i-2j+k) where t is a real parameter. FInd the coordinates of one point which is 6 units from A, and on the line.

I put the equation of the line to parametric form and then, subtracted A from these parametric equations.. but I dont know what I am doing really.

THank you so much!
