Question

Answer 1

\(1\dfrac{4}{5}=-0.15-x\)

\(\Leftrightarrow x+\dfrac{3}{20}=-\dfrac{9}{5}\)

hay \(x=-\dfrac{9}{5}-\dfrac{3}{20}=\dfrac{-36-3}{20}=-\dfrac{39}{20}\)

Answer 2

9/5=-3/20-x

x=-3/20-8/5

x=-39/20

Answer 3

-39/20

Answer 4

\(1\dfrac{4}{5}=-0,15-x\)

<=> \(\dfrac{9}{5}=-0,15-x\)

<=> -x = \(\dfrac{9}{5}+0,15\)

<=> -x = \(\dfrac{39}{20}\)

<=> x = \(\dfrac{-39}{20}\)
