Question

if x and y are two positive numbers' x+y = 220 and the difference between x and y is 20 then fill the correct answer x- y- ​

Answer 1

Answer:

Given that

x+y = 220

x-y =20

Adding both the equations

2x = 240

x =120

Substitute x in equation 2

120-y = 20

y = 120 - 20

y = 100

x = 120, y =100

Answer 2

Answer:

Given that

x+y = 220

x-y =20

Adding both the equations

2x = 240

x =120

Substitute x in equation 2

120-y = 20

y = 120 - 20  

y = 100

x = 120, y =100
