I'd like step by step solution if its possible

the 1st system is this one:

dx+y+z=a

x+dy+z=b

x+y+dz=c

where a,b,c Real Numbers

The Second is this one:

ax+by+z=1

x+aby+z=b

x+by+az=1

Where a,b Real Numbers

Please DONT solve them both, just one of them,

so i ll try the second on my own and then i ll post my

solution, so you can correct my mistakes

Thanks alot in advance for your help people , its really important :-)
