  2. INEQUATION 1

  3. INEQUATION 2 • Tester l’inéquation : • 4x – 3 > 9 – 2x • pour les valeurs suivantes de x : • x = 1 • x = 2 • x = 3

  4. INEQUATION 3 • Tester l’inéquation : • 4 – 3x  4x + 18 • pour les valeurs suivantes de x : • x = 2 • x = -5 • x = -2

  5. INEQUATION 4 • Résoudre les inéquations suivantes : a/ 3x + 5 > -2 b/ 7x + 5 < -3 c/ 8x + 3  6 d/ 7x + 2 > x + 6 e/ 5x + 9 < 3 – 4x
