Question

8(x-14)=56
(46-x)×19=418
9(143-13x)=234
17(5x-16)=238

Answer 1

8(x-14)=56
8х-112=56
8х=56+112
8х=168
х=168:8
х=21

(46-x)×19=418
46-х=418:19
46-х=22
х=46-22
х=24

9(143-13x)=234
143-13х=234:9
143-13х=26
13х=143-26
13х=117
х=117:13
х=9

17(5x-16)=238
5х-16=238:17
5х-16=14
5х=14+16
5х=30
х=30:5
х=6
