Question

The sum of two numbers is 64 and their differences is 10. Find the numbers.

Answer 1

Answer: x = 7, y = 54

Step-by-step explanation:

Let the first no be x

Let the second no be y

x+y = 64

x-y = 10

x = 64-y

(64 - y)-y = 10

64 - 2y = 10

y = 10-64/ -2

y = 5+32

y = 57

x = 64 - y = 64 - 57 = 7

x=7

y=57

Answer 2

Answer:

Step-by-step explanation:

Let no.s be x and y

x+y=64 (i)

x-y=10 (ii)

x=64-y (iii)

Putting (iii) in (ii)

64-y-y=10

64-2y=10

54=2y

y=54/2 =27

x=64-27=37
