ANSWER

_________________________________________

Given:-

\sf{x - y = 2} \: \: \: \: ⇢1x−y=2⇢1

\sf{2x - y + 2 = 0} \: \: \: \: ⇢22x−y+2=0⇢2

_________________________________________

Proof:-

\sf{⇒x = 2 + y \: (from \: 1)}⇒x=2+y(from1)

Substitute the value of x to equation 2

\sf{⇒2(y + 2) - y + 2 = 0}⇒2(y+2)−y+2=0

\sf{⇒2y + 4 - y + 2 = 0}⇒2y+4−y+2=0

\sf{⇒y + 6 = 0}⇒y+6=0

\large\sf{\color{yellow}\boxed{\color{orange}{⇒y = - 6}}} \: \: \: \:

⇒y=−6

Substitute the value of y for equation 1

\sf{⇒x - ( - 6) = 2}⇒x−(−6)=2

\sf{⇒ x + 6 = 2}⇒x+6=2

\sf{⇒x = 2 - 6}⇒x=2−6

\large\sf{\color{yellow}\boxed{\color{orange}{⇒x = - 4}}}

⇒x=−4
