x=\frac{4}{2}
Consider the first equation. Divide both sides by 2.
x=2
Divide 4 by 2 to get 2.
z=2+4
Consider the third equation. Insert the known values of variables into the equation.
z=6
Add 2 and 4 to get 6.
a=6
Consider the fourth equation. Insert the known values of variables into the equation.
x=2 y=4 z=6 a=6
The system is now solved.
