a=60-\frac{20}{2}
Consider the second equation. Insert the known values of variables into the equation.
a=60-10
Divide 20 by 2 to get 10.
a=50
Subtract 10 from 60 to get 50.
b=50
Consider the third equation. Insert the known values of variables into the equation.
c=50
Consider the fourth equation. Insert the known values of variables into the equation.
z=20 a=50 b=50 c=50
The system is now solved.
