Answer 1

$\huge{\bf{\underline{\underline{\colorbox{lavender}{\color{purple} {αиѕωєя}}}}}}$

$\purple\dashrightarrow\sf{3x-y=6, 2x-y=1}$

$\purple\dashrightarrow\sf{x-y= \frac{6}{3} }$

$\purple\dashrightarrow\sf{x-y= 2}$

$\purple\dashrightarrow\sf{x= 2+ y}$

Answer 2

Answer:

⇢3x−y=6,2x−y=1

\purple\dashrightarrow\sf{x-y= \frac{6}{3} }⇢x−y=

3

6

\purple\dashrightarrow\sf{x-y= 2}⇢x−y=2

\purple\dashrightarrow\sf{x= 2+ y}⇢x=2+y
