Question

x+y=20 x-y= 5 which is the number​

Answer 1

Answer:

x= 25/2

y= 15/2

Step-by-step explanation:

x+y= 20

y= 20-x

x-y= 5

Putting value of y

x-20+x = 5

2x= 5+20

x= 25/2

y= 20-x

y= 20-25/2

y= 15/2

Answer 2

Step-by-step explanation:

x+y=20

x=20-y

x-y=5

20-y-y=5

20-2y=5

-2y=5-20

-2y=-15

y=-15/-2

y=15/2

y=7.5

x=12.5
