How to simplify 84-7[-11x-4{-17x+3(5x-1)}]

Answer 1

$\large\mathsf{Hoy !!}$
$<i>$
Given :

84 - 7 [ - 11x - 4 { - 17x + 3 ( 5x - 1 ) } ]

Applying "BODMAS" Rule

Opening ( ) bracket

= 84 - 7 [ - 11x - 4 { - 17x + 15x - 3 } ]

= 84 - 7 [ - 11x - 4 { - 2x - 3 } ]

Opening { } bracket

= 84 - 7 [ - 11x + 8x + 12 ]

= 84 - 7 [ - 3x + 12 ]

Opening [ ] bracket

= 84 + 21x - 84

= 21x

Hence,

The answer is 21x.
