Question

The sum of two nunbers is 45 and their difference is 9. What is the number?​

Answer 1

Step-by-step explanation:

Let the numbbers be a,,b

Their sum is 45

a+b=45

a=45−b

The difference is 9

a−b=9

a=9+b

2a=54

a=27

b=45−27=18

So the numbers are 27,18

Answer 2

Step-by-step explanations

Let nos be x and x+9

x+x+9 = 45

2x= 45-9

2x= 36

x= 36/2

x= 18

nos = 18 and 18+9= 27
