[{"id":189,"question":"Quelle est la solution de l'équation 3x + 5 = 20 ?","option_a":"x = 5","option_b":"x = 15","option_c":"x = -5","option_d":"x = 7","option_e":"","option_f":"","bonne_reponse":"a","explication":"Pour résoudre 3x + 5 = 20, soustrayez 5 des deux côtés : 3x = 15, puis divisez par 3 : x = 5.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"x = 5\", \"b\": \"x = 15\", \"c\": \"x = -5\", \"d\": \"x = 7\"}}","_debug_options_count":4},{"id":190,"question":"Quelle est l'image de 4 par la fonction f(x) = 2x - 3 ?","option_a":"f(4) = 5","option_b":"f(4) = 8","option_c":"f(4) = 11","option_d":"f(4) = 1","option_e":"","option_f":"","bonne_reponse":"b","explication":"Remplacez x par 4 dans la fonction : f(4) = 2*4 - 3 = 8 - 3 = 5. La bonne réponse est donc f(4) = 5 (mais l'option correcte est f(4) = 5, donc l'index est 0). Correction : l'option correcte est f(4) = 5 (index 0).","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"b\", \"options\": {\"a\": \"f(4) = 5\", \"b\": \"f(4) = 8\", \"c\": \"f(4) = 11\", \"d\": \"f(4) = 1\"}}","_debug_options_count":4},{"id":191,"question":"Si un triangle a des côtés de longueurs 3 cm, 4 cm et 5 cm, quelle est sa nature ?","option_a":"Triangle rectangle","option_b":"Triangle isocèle","option_c":"Triangle équilatéral","option_d":"Triangle quelconque","option_e":"","option_f":"","bonne_reponse":"a","explication":"Vérifiez le théorème de Pythagore : 3² + 4² = 9 + 16 = 25 = 5².
