Answer 1

-10.5-30x

Explanation:

explanation is in the image above

Answer 2

`{ \tt{0.5 - 3( - 2x - (1)/(3) + 4 + 8x) }}`

» First solve the bracket by simplification rule. Arrange x terms together and constants together.

`{ \tt{ \dashrightarrow \: 0.5 - 3{ \huge \{}( - 2x + 8x) + (4 - (1)/(3) ){ \huge{ \}}}}}`

» Then solve the sub brackets in the parent bracket:

`\dashrightarrow \: { \tt{0.5 - 3(6x + (11)/(3) )}}`

» Open the bracket following distributive property [ Multiply -3 to each constant in the bracket ]

`\dashrightarrow \: { \tt{0.5 - 18x - 11}}`

» Then simplify:

`{ \tt{ \dashrightarrow \: - (21)/(2) - 18x}} \\`
