Leya [2.2K]

$\qquad \qquad \sf \: \huge Answer♨$

Let's simplify ~

<h3>Expression 1</h3>

$\qquad \sf \dashrightarrow \:2x + 5 + x - 6 + 3x$

$\qquad \sf \dashrightarrow \:(2x + x + 3x) + (5 - 6)$

$\qquad \sf \dashrightarrow \:6x + ( - 1)$

$\qquad \sf \dashrightarrow \:6x - 1$

<h3>Expression 2</h3>

$\qquad \sf \dashrightarrow \:x - 8 + x - 5 + x + 1$

$\qquad \sf \dashrightarrow \:(x + x + x) + ( - 8 + ( - 5) + 1)$

$\qquad \sf \dashrightarrow \:3x + ( - 12)$

$\qquad \sf \dashrightarrow \:3x - 12$
