$\longrightarrow (-\dfrac{1}{2} +2)$

$\longrightarrow (-\dfrac{1}{2} +\dfrac{4}{2} )$

$\longrightarrow \dfrac{-1+4}{2}$

$\longrightarrow \dfrac{3}{2}$

$\sf \bold{\longrightarrow 1\dfrac{1}{2}}$ (final answer)

$\longrightarrow \sf 4(\dfrac{1}{2} +\dfrac{5}{4} ) + (-5)$

$\longrightarrow \sf 4(\dfrac{2}{4} +\dfrac{5}{4} ) + (-5)$

$\longrightarrow \sf 4(\dfrac{7}{4} ) + (-5)$

$\longrightarrow \sf 7-5$

$\longrightarrow \bold{\sf 2}$ (final answer)
