Simplify: $39x–[23x–\{29x–(17x–3x)\left\}\right]$$\left[2Marks\right]$

Answer 1

Given: $39x–[23x–\{29x–(17x–3x)\left\}\right]$

$\Rightarrow 39x–[23x–\{29x–14x\left\}\right]$ [Removing ( ) braces]$\left[1Mark\right]$

$\Rightarrow 39x–[23x–15x]$ [Removing { } braces]

$\Rightarrow 39x–8x$

$\Rightarrow 31x$$\left[1Mark\right]$
