y=0
Consider the first equation. Anything times zero gives zero.
0=3x
Consider the second equation. Insert the known values of variables into the equation.
0=x
Divide both sides by 3. Zero divided by any non-zero number gives zero.
x=0
Swap sides so that all variable terms are on the left hand side.
y=0 x=0 z=5 a=5
The system is now solved.
