Homework Statement
Show that the following equations can be solved for any a:
ax1 + 2x2 + ax3 = 5a
x1 + 2x2 + (2-a)x3 = 5
3x1 + (a+2)x2 + 6x3 = 15
2. The attempt at a solution
I thought I would do gaussian elimination to get it into reduced form (in a coefficient matrix), and see where I can go from there. But I don't know how to do Gaussian elimination because the coefficient of a certrain x1 is a...
Can anybody give a hint?
