**The question is, Solve the equation!** *I think I have solved the first part...*
x = 8

y = -1

z = 3

This is is only one of the solutions: if you write down your augmented matrix, you get after simplifying it (by Gauss's method, say):
As the third row is clearly a scalar multiple of the 2nd one it will vanish in the next step, and the general solution is

As you can see, we wrote x,y as functions of z. Now just write

and we're done.

This solution means: for ANY choice of the parameter t, you plug in this choice above for z and thus for x,y and you'll get a solution.

**But then they say that the answer has to be written as;** Where *a,b,c,d,e,f,g,h* have to be itegers.

I have absolutely no idea how to solve this problem. Please help! What is... **a**=? **b**=?

**c**=?

**d**=?

**e**=?

**f**=?

**g**=?

**h**=?

Thanks!
