We are given,

$\longrightarrow 0.2(10 - 5c) = 5c - 16$

Solving the parenthesis

${ \longrightarrow 0.2 \times 10 - 0.2 \times 5c = 5c - 16 }$

${ \longrightarrow 2 - 1c = 5c - 16 }$

${ \longrightarrow 2 + 16 = 5c + 1c }$

${ \longrightarrow 18 = 6c }$

Dividing both sides by 6

${ \longrightarrow 3 = c }$

Hence c = 3.
