Question

if x-y=2 and x+y=10 then
find the value of X and y
with explain
​

Answer 1

Step-by-step explanation:

x - y = 2 -------------(1)

x + y = 10 -----------(2)

By elimination method, add (1) and (2)

x - y = 2

x + y = 10

____________

2x + 0 = 12

_____________

2x = 12

x = 6

Put in (1)

x - y = 2

6 - y = 2

- y = -4

y = 4

Pls mark it as the brainliest answer and pls follow me friend....

Answer 2

x-y=2

=>x=2+y

and x+y=10

=>x=10-y

hence

2x=(2+y)+(10-y)

2x=2+y+10-y

2x=12

x=12/2

x=6

and y=4
