Question

solve the pair of linear equation X+y=14 x-y=14
​

Answer 1

X+y=14-----(1)

x-y=14--------(2)

adding equation (1)&(2)we get,

2x=28

x=14

putting the Value of X in (1)we get

y=0

Answer 2

$x + y = 14 ........(1)\\ x - y = 14........(2) \\ adding \: both \: equations \\ 2x = 28 \\ x = \frac{28}{2} \\ x = 14 \\ put \: value \: of \: x \: in \: equation \: (1) \\ x + y = 14 \\ 14 + y = 14 \\ y = 14 - 14 \\ y = 0$
