X: 0.1 + X : 0.5 - X : 25% + X + X = 2019
\(x:0,1+x:0,5-x:25\%+x+x=2019\)
\(\Rightarrow10x+2x-x:0,25+2x=2019\)
\(\Rightarrow12x-4x+2x=2019\)
\(\Rightarrow10x=2019\)
\(\Rightarrow x=201,9\)
x : 0,1 + x : 0,5 - x : 25 % + x + x = 2019 (dấu chấm lầ dấu nhân)
x . 10 + x . 2 - x : 0,25 + x + x = 2019
x . 10 + x . 2 - x . 4 + x + x = 2019
x . ( 10 + 2 - 4 + 1 + 1 ) = 2019
x . 10 = 2019
x = 2019 : 10
x = 201,9
Vậy x = 201,9
Trả lời
\(x\div0,1+x\div0,5-x\div25+x+x=2019\)
\(x\times10+x\times2-x\div0,25+x+x=2019\)
\(x\times10+x\times2-x\times4+x+x=2019\)
\(x\times\left(10+2-4+1+1\right)=2019\)
\(x\times10=2019\)
\(x=201,9\)
Vậy \(x=201,9\)
