Question

x x 2019 - x = 2018 x 2018 + 2018

Ai nhanh, đúng và chính xác nhất mik tick ^^

Answer 1

\(x\times2019-x=2018\times2018+2018\)

\(x\times\left(2019-1\right)=2018\times\left(2018+1\right)\)

\(x\times2018=2018\times2019\)

\(\Rightarrow x=2019\)

Answer 2

X x 2019 - x =2018 x 2018 + 2018

X x(2019-1) = 2018 x(2018 + 1)

X x 2018 = 2018 x 2019

=> X=2019

Vậy X=2019.

Answer 3

Mơn mấy bn ^^ 

Answer 4

X=2019

Answer 5

\(x\times2019-x=2018\times2018+2018\)

\(\Rightarrow x\times\left(2019-1\right)=\left(2018+1\right)\times2018\)

\(\Rightarrow x\times2018=2019\times2018\)

\(\Rightarrow x=2019\)

Vậy \(x=2019\)
