Question

-(n-x)-x р+(-m+R-p) -a-(m-a+p) -(m-a)-(R+a)

Answer 1

$1) - (n-x)-x=-n+x-x=-n$
$2) p+(-m+r-p)=p-m+r-p=-m+r$

$3) -a-(m-a+p)=-a-m+a-p=-m-p$
$4) -(m-a)-(r+a)=-m+a-r-a=-m-r$

Answer 2

Let's simplify the given expression step by step:

-(n-x) - x + (-m+R-p) - a - (m-a+p) - (m-a) - (R+a)

Step 1: Distribute the negative sign in the first term and simplify: -(n) + x - x + (-m+R-p) - a - (m-a+p) - (m-a) - (R+a)

Step 2: Combine like terms: x - x = 0, so we can eliminate those terms: -(n) + (-m+R-p) - a - (m-a+p) - (m-a) - (R+a)

Step 3: Distribute the negative sign in the second term and simplify: -(n) - m + R - p - a - (m-a+p) - (m-a) - (R+a)

Step 4: Combine like terms: -(n) - m + R - p - m + a - p - (R+a)

Step 5: Distribute the negative sign in the third term and simplify: -(n) - m + R - p - m + a - p - R - a

Step 6: Combine like terms: -(n) - m - m + R - R + a - a - p - p

Step 7: More simplification: -n - 2m - 2p

So, the simplified expression is: -n - 2m - 2p
