x=\frac{21}{3}
Consider the first equation. Divide both sides by 3.
x=7
Divide 21 by 3 to get 7.
y=7
Consider the second equation. Insert the known values of variables into the equation.
z=7
Consider the third equation. Insert the known values of variables into the equation.
x=7 y=7 z=7
The system is now solved.
