Question

linear equation x+y=4​

Answer 1

Let x be 2

Now,

lets put the value in the place of x .

like this :-

x + y = 4

=> 2+y=4

=> y = 4-2

=> y = 2

1 point :-

[{ x = 2}{y = 2}

2nd point :-

let's put y = 1

Now let's put the values ,

like this :-

=> X+1=4

=> X = 4-1

=> X = 3

So another point is

( X = 3 , y = 1 )

Answer 2

$x + y = 4$

$x = 4 - y$

$if \: \: y = 1$

$x = 4 - 1$

$x = 3$

$if \: \: \: y = 2$

$x = 4 - 2$

$x = 2$

$if \: \: y \: = 3$

$x = 4 - 3 \\ = 1$

$\therefore The \: \: coordinates \: \: are </p><p>(3,1), \: (2,2), \: (1,3)$
