Explicație pas cu pas:
xy + 2y - 3x = 5 ;
x = 1 => y+2y-3 = 5 => 3y = 8 => y = 8/3 ∈ Q
x = 2 => 2y+2y-6 = 5 => 4y = 11 => y = 11/4 ∈ Q
x = 3 => 3y+2y-9 = 5 => 5y = 14 => y = 14/5 ∈ Q
x = 4 => 4y+2y-12 = 5 => 6y = 17 => y = 17/6 ∈ Q
x = 5 => 5y+2y-15 = 5 => 7y = 20 => y = 20/7 ∈ Q
x = 6 => 8y = 23 => y = 23/8 ∈ Q
x = 7 => 9y = 26 => y = 26/9 ∈ Q
