Answer 1

Answer:

the sum of two number is 20

their difference is 4 =20-4=16

the greater of the two numbers is 16

Answer 2

Step-by-step explanation:

Let first number be x

second. number is y

according to the question x+y=20 (i)

and x-y=4(ii) x=4+y

so,Substituting the value of x from Eq..2 to Eq..1

x + y = 20

4 + y + y = 20

4 + 2y = 20

2y = 20 - 4

2y = 16

y = 16/2

y = 8

Substituting the value of y in Eq. 2 to derive value of x

x = 4 + y

x = 4 + 8

x = 12

Thus the two numbers are 12 and 8. Out of two the number 12 is greater
