x=\frac{18}{6}
Consider the first equation. Divide both sides by 6.
x=3
Divide 18 by 6 to get 3.
y=3+0
Consider the second equation. Insert the known values of variables into the equation.
y=3
Add 3 and 0 to get 3.
z=3
Consider the third equation. Insert the known values of variables into the equation.
a=3
Consider the fourth equation. Insert the known values of variables into the equation.
x=3 y=3 z=3 a=3
The system is now solved.
