2x=10
Consider the first equation. Combine x and x to get 2x.
x=\frac{10}{2}
Divide both sides by 2.
x=5
Divide 10 by 2 to get 5.
y=5
Consider the second equation. Insert the known values of variables into the equation.
z=5
Consider the third equation. Insert the known values of variables into the equation.
a=5
Consider the fourth equation. Insert the known values of variables into the equation.
x=5 y=5 z=5 a=5
The system is now solved.
