User: Simplify (x - y + 1) - (x + y - 1).

Weegy: (x - y + 1) - (x + y - 1)
= x - y + 1 - x - y + 1
= (x - x) + (-y - y) + (1 + 1)
= -2y + 2

User: Simplify (3x + 5) + (2x - 9) - (4x + 3)

Weegy: (3x + 5) + (2x - 9) - (4x + 3)

= (5x - 4) - (4x + 3)

= (5x - 4) + (-4x - 3)

= x - 7

User: Simplify -(-2a + 13) + (-9a - 2) - (-7a - 3)

Weegy: -(-2a + 13) + (-9a - 2) - (-7a - 3)
= 2a - 13 - 9a - 2 + 7a + 3
= -12

User: Simplify 3j - {2k - [5h - (3j + k)]}.

Weegy: 3j - {2k - [5h - (3j + k)]}

= 5h - 3k

User: Simplify {n - 1 - [n - 1 - (n - 1)]}.

User: Simplify a - {5b - [a - (3b - 2c) + c - (a - 2b - c)]}.

Weegy: a - {5b - [a - (3b - 2c) + c - (a - 2b - c)]}
= a - [5b - (a - 3b + 2c + c - a + 2b + c)]
= a - [5b - (-b + 4c)]
= a - (5b + b - 4c)
= a - (6b - 4c)
= a - 6b + 4c

User: Simplify 2m - [n - (m - 2n)].

Weegy: 2m - [n - (m - 2n) is equal to 3m -3n.
SOLUTION:
2m - [n - (m - 2n)].
2m - [n - m + 2n].
2m - n + m - 2n.
2m + m - n - 2n.
3m - 3n.

{n - 1 - [n - 1 - (n - 1)]}
= {n - 1 - (n - 1 - n + 1)}
= {n - 1 - 0}
= n - 1

11 - 2m-(n + 5+-m - 3n + 8)
=(-2m + m)+(- n + 3n)+(11 +(-5)+(-8))
= - m + 2n - 2
