Answer:
[tex]{ \tt{0.5 - 3( - 2x - \frac{1}{3} + 4 + 8x) }}[/tex]
» First solve the bracket by simplification rule. Arrange x terms together and constants together.
[tex]{ \tt{ \dashrightarrow \: 0.5 - 3{ \huge \{}( - 2x + 8x) + (4 - \frac{1}{3} ){ \huge{ \}}}}}[/tex]
» Then solve the sub brackets in the parent bracket:
[tex] \dashrightarrow \: { \tt{0.5 - 3(6x + \frac{11}{3} )}} [/tex]
» Open the bracket following distributive property [ Multiply -3 to each constant in the bracket ]
[tex] \dashrightarrow \: { \tt{0.5 - 18x - 11}}[/tex]
» Then simplify:
[tex]{ \tt{ \dashrightarrow \: - \frac{21}{2} - 18x}} \\ [/tex]
