Question

1.11 – [ 2 + { 3 – ( x – 9 ) } ]

2. 6 – { 4 – ( p – 8) }

please answer ​

Answer 1

Step-by-step explanation:

1.

=11-[2+{3-x+9}]

=11-(2+3-x+9)

=11-(14-x)

=11-14+x

so,x=-3

2.

=6-{4-p+8}

=6-4+p-8

=p+6-12

=p-6

so,p= 6

Answer 2

Answer:

x-3; p-6

Working:

Start with innermost bracket and work your way out

1. 11 - [2 + {3 - x + 9}]

= 11 - [2 + {12 - x}]

= 11 - [2 + 12 - x]

= 11 - [14 - x]

= 11 - 14 + x

= x - 3

2. 6 - {4 - p + 8}

= 6 - {12 - p}

= 6 - 12 + p

= p - 6

To check, put a value in the question and answer and you should get the same values for both.
