Question

solve
1)x+y=14
2)x-y=2​

Answer 1

adding the two equations, we get,

2x = 16

x = 8

putting the value of x in the first equation,we get

8 + y = 14

y = 6

Answer 2

$x + y = 14 \\ x + y - 14 = 0 \: \: \: \: \: \: \: (1)$

$x - y = 2 \\ x - y - 2 = 0 \: \: \: \: \: (2)$

$x + y - 14 = x - y - 2 \\ x - x + y + y = - 2 + 14 \\ 2y = 12 \\ y = \frac{12}{2} \\ y = 6$

$x + y = 14 \\ x + 6 = 14 \\ x = 14 - 6 \\ x = 8$
