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*113-2018*14
D = 2018 + 2018 x 113 - 2018 x 14

x : 0,1 +x: 0,25 + x: 0,5 + x× 4 =2018
Bài làm
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
