Х : 8 = 49 52+72 : x =56 ( x - 23 ) : 26 =8 1728 : ( 56 - x ) = 36

Question

Х : 8 = 49
52+72 : x =56
( x - 23 ) : 26 =8
1728 : ( 56 - x ) = 36

Answer 1

1) х = 49×8
х = 392
2) х = (52+72) ÷ 56
х = 124 ÷ 56
х = 2 3/14
3)х- 23 = 26×8
х - 23 = 208
х = 208+23
х = 231
4)56- х = 1728 ÷ 36
56 -х = 48
х = 56- 48
х = 8
