Can u saolve the questions given above? ​

Answer 1

Answer:

Step-by-step explanation:

Given that,

p+ ( - q - r - s ) - ( p - q - r )

= p - q - r - s - p + q + r (∵ + × - = - ; - × + = - ; - × - = + )

= ( p - p ) + ( - q + q ) + ( - r + r ) - s ( ∵ like terms )

= 0 + 0 + 0 - s

= - s is the answer.
