Question

The solution of the following pair of linear equations x – y= 2 & x+y= 4 is___________

Answer 1

solve with question step by step

Answer 2

x=3

y=1

Step-by-step explanation:

$x - y = 2 \\ x +y = 4 \\ h \\ by adding these \: 2 \: equations \: \\ y - y = 0 \\ then2x = 6 \\ x = 6 \div 2 \\ x =3 \\ paste \: x = 3 \: in 1st \: equation \\ 3- y = 2 \\ - y = 2 - 3 \\ - y = - 1 \\ - sign \: is \: balanced \\ y = 1$

$x = 3 \\ y = 1$
