Question

Реши уравнение.
1) (134+34):14-x=132:22+6
2) 240:(x-18)=226-106

Answer 1

(134+34):14-Х=132:22+6                     240:(х-18)=226-106

(134+34):14-х=12                                 240:(х-18)=120

168 :14-х=12                                         х-18=240:120               

12-х=12                                                 х-18=2

 х=12-12                                                х=18+2

х=0                                                         х=20

Answer 2

1) 168:14-х=6+6
12-х=12
х=12-12
х=0

2) 240:(х-18)=120
х-18=240:120
х-18=2
х=2+18
х=20
