X:0,1+X:0,25+X:0,5+X×4
⇒ x :0,1+ x :0,25+ X:0,5+x:0,25=2018
⇒ X:(0,1+0,25+0,5+0,25)=2018
⇒ X:1,1=2018
⇒ x=2018 x1,1=2219,8
Vậy X=2219,8

D = 2018 + 2018 x 113 - 2018 x 14
= 2018 x ( 1 + 113 - 14 )
= 2018 x 100
= 201 800

X : 0,1 + X : 0,25 + X : 0,5 + X x 4 = 2018
X x 10 + X x 4 + X x 2 + X x 4 = 2018
X x ( 10 + 4 + 2 + 4 ) = 2018
X x 20 = 2018
X = 2018 : 20
X = 100,9
Vậy X = 100,9

Khó quá zậy
Nhưng mình bít kết quả rồi
đó là : -1,002482622
2018 : 0,2 + 2018 x 0,5 + 2018 x 0,25 + 2018 x 89
= 2018 x 5 + 2018 x 0,5 + 2018 x 0,25 + 2018 x 89
= 2018 x ( 5 + 0,5 + 0,25 + 89 )
= 2018 x 94,75
= 191205,5
Study well ! >_<
2018 : 0,2 + 2018 x 0,5 + 2018 x 0,25 + 2018 x 89
= 2018 x 5 + 2018 x 0,5 + 2018 x 0,25 + 2018 x 89
= 2018 x ( 5 + 0,5 + 0,25 + 89 )
= 2018 x 94,75
= 191205,5
