Question

Как решить 36:(×-2)=4 и 25(×+15)=432

Answer 1

36 : (х - 2) = 4                25 (х + 15) = 432 

х - 2 = 36 : 4                   х + 15 = 432 : 25          

х - 2 = 9                          х + 15 = 17,28                

х = 9 + 2                         х = 17,28 - 15

х = 11                             х = 2,28 

Answer 2

36:(х-2)=4
х-2=36:4
х-2=9
х=9+2
х=11
Ответ: х=11

25(х+15)=432
х+15=432:25
х+15=17,28
х=17,28-15
х=2,28
