Answer 1

$\huge\bf\underline{\underline{Question}}$

Simplify:

(x + y - 2) + ( + z-x) + (2 + x - y)

$\huge\bf\underline{\underline{Solution}}$

= (x + y - 2) + ( + z-x) + (2 + x - y)

= x + y - 2 + z-x + 2 + x - y

+x and - x is cancelled, +y and - y is cancelled, also +2 and - 2 is cancelled.

Therefore we are left with,

= x + z
