Answer 1

`\Huge \boxed{60}`

`\rule[225]{225}{2}`

Explanation:

`2(3n-9)`

The value of n is 13.

`\Longrightarrow \ \ 2(3(13)-9)`

Solving for brackets,

`\Longrightarrow \ \ 2(39-9)`

`\Longrightarrow \ \ 2(30)`

Multiplying,

`\Longrightarrow \ \ 60`

`\rule[225]{225}{2}`

Answer 2

Steps to solve:

2(3n - 9); n = 13

~Substitute

2(3(13) - 9)

~Simplify

2(39 - 9)

~Subtract

2(30)

~Multiply

60
