The answer is 2x

(x-2y+3) + (x+2y-3)

=x-2y+3+x+2y-3

=2x-2y+2y+3-3

=2x is the answer

Hope it helps........

Answer 2

Answer:

$\left(x-2y+3\right)+\left(x+2y-3\right)=2x$

Step-by-step explanation:

$\left(x-2y+3\right)+\left(x+2y-3\right)$

$\gray{\mathrm{Remove\:parentheses}:\quad \left(a\right)=a}$

$=x-2y+3+x+2y-3$

$\gray{\mathrm{Group\:like\:terms}}$

$=x+x-2y+2y+3-3$

$\gray{\mathrm{Add\:similar\:elements:}\:x+x=2x}$

$=2x-2y+2y+3-3$

$\gray{\mathrm{Add\:similar\:elements:}\:-2y+2y=0}$

$=2x+3-3$

$\gray{3-3=0}$

$=2x$
