Answer 2

\(\frac{x+2019}{x+2018}=\frac{4038}{4037}\)

\(\Leftrightarrow4037(x+2019)=4038(x+2018)\)

\(\Leftrightarrow4037x+8150703=4038x+8148684\)

\(\Leftrightarrow4037x+8150703-4038x=8148684\)

\(\Leftrightarrow4037x-4038x+8150703=8148684\)

\(\Leftrightarrow-x=-2019\)

\(\Leftrightarrow x=2019\)

Answer 3

\(\frac{x+2019}{x+2018}=\frac{4038}{4037}\)

\(\Rightarrow4037.\left(x+2019\right)=4038.\left(x+2018\right)\)

\(4037x+8150703=4038x+8148684\)

\(4038x-4037x=8150703-8148684\)

\(x=2019\)
