a) ( x + 268 ) x 137 = 48498
( x + 268 ) = 48498
x + 268 = 354
x = 354 - 268
x = 86
137 x 82 + 137 x 9 + 137 x 8 + 137 = 13700
56 - ( x - 14 ) = 22
x - 14 = 56 - 22
x - 14 = 34
x = 34 + 14
x = 48
172 - ( 137 - x ) = 93
137 - x = 172 - 93
137 - x = 79
x = 137 - 79
x = 58
1/ 56 - (x - 14) = 22 => x - 14 = 56 - 22 => x - 14 = 34 => x = 34 + 14 => x = 48
2/ 172 - (137 - x) = 93 => 137 - x = 172 - 93 => 137 - x = 79 => x = 137 - 79 => x = 58
( 137 x 57 + 687 x 86 ) : ( 26 x 13 + 74 x 16 )
= ( 7809 + 59082 ) : ( 338 + 1184 )
= 66891 : 1522
= 43.94940867279895
(2011/2012+2012/2013+2013/2014+...+3026/3027) x (1/5-2/3:3/10)
= (2011/2012+2012/2013+2013/2014+...+3026/3027) x (1/5-2/10)
= (2011/2012+2012/2013+2013/2014+...+3026/3027) x (1/5-1/5)
= (2011/2012+2012/2013+2013/2014+...+3026/3027) x 0
= 0
x.24=3027+2589
x.24=5616
x =5616:24
x =234
Hình như câu 2 sai đề
