Question

85- [12x- 7(8x- 3)-2{10x- 5(2- 4x)}]

Answer 1

Step-by-step explanation:

First we have to remove the parentheses, then remove braces, and then the square brackets.

Then we get, = 85 – [12x – 7(8x – 3) – 2{10x – 5(2 – 4x)}] = 85 – [12x – 56x + 21 – 2{10x – 10 + 20x}] = 85 – [12x – 56x + 21 – 2{30x – 10}] = 85 – [12x – 56x + 21 – 60x + 20] = 85 – [12x – 116x + 41]

= 85 – [- 104x + 41]

On simplifying further

= 85 + 104x – 41

= 44 + 104x
