Largeur = x
longueur = 4 x
2 ( x + 4 x) = 20
2 x + 8 x = 20
10 x =20
x = 2
largeur = 2 et longueur = 8
(1,3) means that x = 1 and y = 3. Let's make substitutions to see what happens with the inequality
5*x + y < -3
5*1 + y < -3 ... replace x with 1
5*1 + 3 < -3 ... replace y with 3
5 + 3 < -3
8 < -3
This is false. The number 8 is NOT smaller than -3.
So (1,3) is NOT a solution
