Question

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

• A. $30x$
• B. $31x$
• C. $29x$
• D. $33x$

Answer 1

The correct option is B

$31x$

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

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

$\Rightarrow 39x–[23x–\{29x–14x\left\}\right]$

$\Rightarrow 39x–[23x–15x]$

$\Rightarrow 39x–8x$

$\Rightarrow 31x$
