# Help with 3x3 system question watch

1. 5x+3y+2z=13
x+y+z=3
2y+3z=2

I think I've found a solution of z=2(x-2), y=7-3x. Could someone tell me whether this is correct and that this is all i need to do. If it is wrong i will post my working and help may be required if available.

N.B. question states use gaussian elimination to find the most general form the solution.

Yeah, that's correct. If I were you, I'd put it in the form of a line. By letting you have your solution line as .

As a check you can always substitute back into the original equations to see if your solution satisfies them.
