Disebuah kampus ada enam mahasiswa yakni : Ani, Bela, Citra, Dina, Endang, Fina.

{ x 2 + y 2 = 25 2 x + y = 10 ​ { x 2 + y 2 = 25 y = 10 − 2 x ​ { x 2 + ( 10 − 2 x ) 2 = 25 y = 10 − 2 x ​ { x 2 + 100 − 40 x + 4 x 2 = 25 y = 10 − 2 x ​ { 5 x 2 − 40 x + 75 = 0 y = 10 − 2 x ​
{ x 2 − 8 x + 15 = 0 y = 10 − 2 x ​ { Δ = ( − 8 ) 2 − 4 ∗ 1 ∗ 15 = 64 − 60 = 4 ; Δ ​ = 2 y = 10 − 2 x ​ { x 1 ​ = 2 8 − 2 ​ = 3 ∧ x 2 ​ = 2 8 + 2 ​ = 5 y = 10 − 2 ∗ 3 = 4 ∧ y = 10 − 2 ∗ 5 = 0 ​

The solution set for the system of equations is {(3, 4), (5, 0)}. This was found by substituting one equation into the other and solving the resulting quadratic equation. Finally, the corresponding y-values were calculated for each x-value found.
