Given $x = 2$ $x=2$
we can substitute $2$ $2$ for the variable $x$ $x$ in the second equation:
$2 x + y = 1$ $2x+ y =1$
giving
$2 (2) + y = 1$ $2(2) + y = 1$
$\to y = - 3$ $rarr y= -3$

So $(x, y) = (2, - 3)$ $(x,y) = (2,-3)$

Simply u have to put x=2 in the given equation and u can find the value of y.

In this equation,
putting x=2,we get
$2 (2) + y = 1$ $2(2)+y=1$ ,
now,solve the equation,and u get
$y = - 3$ $y=-3$
so now,x=2
and y=-3.

Thank u!
