Question

write value s of x and y if x+y=2 and x-y=8​

Answer 1

Answer:

x= 5 y= -3

Step-by-step explanation:

x+y+x-y=10

2x=10

x=5

putting the value of x in x+y=2

5+y=2

y=2-5

y= -3

Answer 2

Answer:

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

x-y=8------(2)

Adding equation (1) and (2)

x+y=2

x-y=8

_________

2x=10

x=10/2

x=5

Substituting x=5 in equation (1)

x+y=2

5+y=2

y=2-5

y=-3

(x,y)= (5,-3)
