Answer 1

$\\ \sf\longmapsto \[4x-\overline{3x-5y}-3\{2x-(3x-\overline{2x-3y})\}\]$

$\\ \sf\longmapsto \[4x-3x+5y-3\{2x-(3x-2x+3y)\}\]$

$\\ \sf\longmapsto \[x+5y-3\{2x-(x+3y)\}\]$

$\\ \sf\longmapsto \[x+5y-3\{2x-x-3y\}\]$

$\\ \sf\longmapsto \[x+5y-3(x-3y)\]$

$\\ \sf\longmapsto \[x+5y-3x+9y\]$

$\\ \sf\longmapsto x-3x+5y+9y$

$\\ \sf\longmapsto -2x+14y$

$\\ \sf\longmapsto 14y-2x$
