2x=21-5
Consider the first equation. Subtract 5 from both sides.
2x=16
Subtract 5 from 21 to get 16.
x=\frac{16}{2}
Divide both sides by 2.
x=8
Divide 16 by 2 to get 8.
y=8
Consider the second equation. Insert the known values of variables into the equation.
z=8
Consider the third equation. Insert the known values of variables into the equation.
x=8 y=8 z=8
The system is now solved.
