Answer 1

1) 8(х-14)=56,
х-14=56:8,
х-14=7,
х=7+14,
х=21;
2) (46-х)·19=418,
 46-х=418:19,
 46-х=22,
 х=46-22,
х=24;
3) 9·(143-13х)=234,
 143-13х=234:9,
 143-13х=26,
13х=143-26,
13х=117,
х=117:13,
х=9;
4) 17(5х-16)=238,
 5х-16=238:17,
 5х-16= 14,
 5х=14+16,
5х=30,
х=30:5,
х=6.

Answer 2

1) 8x-112=56
8x=56+112
8x=168
x=21

2) (46-x)×19=418
874-19x=418
-19x=418-874
-19x=-456
x=24

3) 9(143-13x)=234
1287-117x=234
-117x=234-1287
-117x=-1053
x=9

4) 17(5x-16)=238
85x-272=238
85x=238+272
85x=510
x=6
