Question

the sum of two integers is 45. If one of them is 21, find the other.​

Answer 1

Answer:

24

Step-by-step explanation:

let the other integer be x

A.T.Q

21 + x = 45

x = 45 - 21

x = 24

Answer 2

Answer:

24

Step-by-step explanation:

sum of 2 integers is 45 and one of them is 21 so ,

21+other integer =45

if other integer is a

21+a=45

a=45-21

a =24

or

21+a-21=45-21  (subtracting the same number on both sides does not change the value)

a=24
