7x=0
Consider the first equation. Combine 3x and 4x to get 7x.
x=0
Divide both sides by 7. Zero divided by any non-zero number gives zero.
y=0
Consider the second equation. Insert the known values of variables into the equation.
z=0
Consider the third equation. Insert the known values of variables into the equation.
x=0 y=0 z=0
The system is now solved.
