[{"id":2155,"question":"Quelle est la solution de l'équation 3x - 7 = 2x + 5 ?","option_a":"x = 12","option_b":"x = 2","option_c":"x = -12","option_d":"x = 5","option_e":"","option_f":"","bonne_reponse":"a","explication":"Pour résoudre 3x - 7 = 2x + 5, on soustrait 2x des deux côtés (x - 7 = 5), puis on ajoute 7 (x = 12). C'est une équation du premier degré classique.","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 = 12\", \"b\": \"x = 2\", \"c\": \"x = -12\", \"d\": \"x = 5\"}}","_debug_options_count":4},{"id":2156,"question":"Dans un triangle ABC, si l'angle A mesure 50° et l'angle B mesure 60°, quelle est la mesure de l'angle C ?","option_a":"70°","option_b":"110°","option_c":"130°","option_d":"50°","option_e":"","option_f":"","bonne_reponse":"a","explication":"La somme des angles d'un triangle est toujours 180°. Donc 180° - 50° - 60° = 70°.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"70°\", \"b\": \"110°\", \"c\": \"130°\", \"d\": \"50°\"}}","_debug_options_count":4},{"id":2157,"question":"Quelle est l'aire d'un rectangle de longueur 8 cm et de largeur 5 cm ?","option_a":"40 cm²","option_b":"26 cm²","option_c":"13 cm²","option_d":"30 cm²","option_e":"","option_f":"","bonne_reponse":"a","explication":"L'aire d'un rectangle se calcule par la formule Longueur × Largeur.
