v=\frac{23+57}{4}
Consider the second equation. Insert the known values of variables into the equation.
v=\frac{80}{4}
Add 23 and 57 to get 80.
v=20
Divide 80 by 4 to get 20.
w=20
Consider the third equation. Insert the known values of variables into the equation.
u=23 v=20 w=20
The system is now solved.
