Answer:

Simplify the expression.

2 x − 4

[tex]\bold{-2[9-(x+7)] = -4+2x}[/tex]

Solution:

Given, -2[9-(x+7)]

According to the BODMAS rule,

Multiplying the sign inside the brackets we get,

[tex]\Rightarrow -2[9-x-7][/tex]

On subtracting 9 from 7 we get,

[tex]\Rightarrow -2[2-x][/tex]

On multiplying (-2) inside the brackets,

[tex]\Rightarrow -2\times2-(-2\times x)[/tex] (distributive property)

[tex]\Rightarrow (-4+2\times x)[/tex]

[tex]\Rightarrow (-4+2x)[/tex]
