Answer 1

Answer:

The number are 12 and 8.

12 is greater than 8

Step-by-step explanation:

Let number and a and b

According to question:

a + b = 20 --(1)

a - b = 4 --(2)

a = (4 + b)  --(3)

Put value of a in eq.--(1)

4 + b + b = 20

4 + 2b = 20

2b = 20 - 4

2b = 16

b = 16/2

b = 8

Put value of b in eq.--(3)

a = 4 + 8

a = 12

Answer 2

x+y=20

x-y =4

by solving

x=12,y=8

greater no. is 12
