Verify the following?​

Answer 1

Step-by-step explanation:

$\\ \qquad\quad\sf{:}\longrightarrow -20+\left(\dfrac{3}{-5}+\dfrac{7}{10}\right)=\left(-20+\dfrac{3}{-5}\right)+\dfrac{7}{10}$

$\\ \qquad\quad\sf{:}\longrightarrow \dfrac{-200-6+7}{10}=\dfrac{-200-6+7}{10}$

$\\ \qquad\quad\sf{:}\longrightarrow \dfrac{-199}{10}=\dfrac{-199}{10}$

$\\ \qquad\quad\sf{:}\longrightarrow -19.9=-19.9$
