Answer:

$\fbox{ \huge{ \sf{ a = - 8}}}$

Explanation:

$\bigstar{ \sf{ \: 19 = - 3a - 5}}$

$\tt{Step \: 1 \: }$ : Swap the sides of the equation

$\longmapsto{ \sf{ - 3a - 5 = 19}}$

$\tt{Step \: 2 \: }$ : Move 5 to right hand side and change it's sign

$\longmapsto{ \sf{ - 3a = 19 + 5}}$

$\tt{Step \: 3 \: }$ : Add the numbers : 19 and 5

$\longmapsto{ \sf{ - 3a = 24}}$

$\tt{Step \: 4 \: }$ : Divide both sides by -3

$\longmapsto{ \sf{ ( - 3a)/( - 3) = (24)/( - 3)}}$

$\tt{Step \: 4}$ : Calculate

$\longmapsto{ \sf{a = - 8}}$

$\sf ∴ \: the \: value \: of \: a \: is \: - 8.$
