1) 135 +(121-x) = 231
2) x - 32 chia 16 = 48
135 + ( 121 - x ) = 231
121 - x = 231 - 135
121 - x = 96
x = 121 - 96
x = 25
x - 32 : 16 = 48
x- 2 = 48
x= 48 + 2
x = 50
tim x:
a, x/4 + x/8 + x/16 + x/32 + x/64 + x/178=63/128
b, x* (2/5+2/15+2/125+2/135+2/405)=424/405
Tim x
a) X x 15 + X x 13 = 560 x 45
( X + X x 2 ) : 34 = 504
360 : X - 126 : X = 6
58 x X - 934 = 6722
14968 - X x 5 = 4968
tim x ( trong phep chia co dư)
a x : 135 = 204 ( dư 108 )
b 2005 : x = 16 ( dư 37 )
a) x : 135 = 204 (dư 108)
x = 204 x 135 + 108
x = 27 540 + 108
x = 27 648
b) ko biết
\(a,x:135=204\left(dư108\right)\Rightarrow x=204x135+108\)\(=27648\)
\(b,2005:x=16\left(dư37\right)\Rightarrow x=\left(2005-37\right):16=123\)
a) x : 135 = 204 ( dư 108 )
-->x=204*135+108=27648
b) 2005 : x = 16 ( dư 37 )
-->x=(2005-37):16=123
