Question

The difference between two numbers is 18.If their sum is 86 what are the numbers?
Answer in one variable plz...
And do it fast I need it urgently...

Answer 1

Define x:

Let one number be x

The difference between two numbers is 18

⇒ The other number is x + 18

Form equation:

The sum of the two numbers is 86

⇒ x + (x + 18) = 86

Solve x:

x + (x + 18) = 86

Remove bracket:

x + x + 18 = 86

Combine like terms:

2x + 18 = 86

Subtract 18 from both sides:

2x = 68

Divide both sides by 2:

x = 34

Find the numbers:

one number = x = 34

The other number = x + 18 = 34 + 18 = 52

Answer: The two numbers are 34 and 52

Answer 2

$\bf \LARGE \it Hey \: User!!!$

according to the question, the difference between two numbers is 18.

let the two numbers be x and y.

therefore y - x = 18
>> y = x + 18 …(i)

and their sum is 86.

>> y + x = 86 …(ii)

substitute (i) in (ii)

>> x + 18 + x = 86
>> 2x + 18 = 86
>> 2x = 86 - 18
>> 2x = 68
>> x = 68/2
>> x = 34

hence, the two numbers are :-

◾x = 34
◾y = x + 18 = 34 + 18 = 52
