Question

Anyone understand the answer

Answer 1

$\bf 2\frac{1}{2}\left( 8x-\cfrac{4}{5} \right)=-62\implies \cfrac{5}{2}\left( 8x-\cfrac{4}{5} \right)=-62\implies \stackrel{\textit{distributing}}{\cfrac{5\cdot 8}{2}x-\cfrac{5\cdot 4}{2\cdot 5}}=-62 \\\\\\ 20x-2=-62\implies 20x=-60\implies x=\cfrac{-60}{20}\implies x=-3$
