Answer:


\boxed{ \bold{ \huge{ \boxed{ \sf{a = - 11}}}}}

Explanation:


\sf{4a - 2(3a + 8) = 6}

Distribute 2 through the parentheses


\longrightarrow{ \sf{4a - 6a - 16 = 6}}

Collect like terms


\longrightarrow{ \sf{ - 2a - 16 = 6}}

Move 16 to right hand side and change it's sign


\longrightarrow{ \sf{ - 2a = 6 + 16}}

Add the numbers: 6 and 16


\longrightarrow{ \sf{ - 2a = 22}}

Divide both sides by 2


\longrightarrow{ \sf{ ( - 2a)/( - 2) = (22)/( - 2)}}

Calculate


\longrightarrow{ \sf{a = - 11}}

Hope I helped !

Best regards! :D
