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 answers:x=______,y=_________?​

Answer 1

Answer: 120 , 100

Step-by-step explanation:

x + y = 220 (1)

x- y = 20 (2)

(1) + (2) we have

2x = 240

x = 120

y = 120 - 20 = 100

Answer 2

Step-by-step explanation:

Given ,

x + y= 220

X= x

Y = x + 20

x + x + 20 = 220

2x = 220 - 20

2x = 200

x = 100

Therefore , X = x = 100

Y = x + 20 = 120
