tìm số tự nhiên x sao cho x +2019/ x+ 2018= 4038/4037

Answer 1

[Đoàn Trần Quỳnh Hương]

$(x+2019)\; x4037=(x+2018)\; x4038$

$\Rightarrow 4037x+\left(4037\times 2019\right)=4038x+\left(4038\times 2018\right)$

$\Rightarrow 4037x+8150703=4038x+8148684$

$\Rightarrow 4037x-4038x=-8150703+8148684$

⇒−�=−2019

$\Rightarrow x=2019$

Answer 2

[Trần Trung Đạt]

$x+2019)\; x4037=(x+2018)\; x4038$

$\Rightarrow 4037x+\left(4037\times 2019\right)=4038x+\left(4038\times 2018\right)$

$\Rightarrow 4037x+8150703=4038x+8148684$

$\Rightarrow 4037x-4038x=-8150703+8148684$

⇒−�=−2019

$\Rightarrow x=2019$
