Question

5. The sum of two integers is -20. If one of them is 65, find the other.​

Answer 1

Answer:

Given :-

• The sum of two integers is - 20.
• One of the integers is 65.

To Find :-

• What is the other integers.

Solution :-

Let,

➲ The others integers be x

As we know that :

★ Sum of two numbers = One of the integers + Other integers ★

Given :

• Sum of two integers = - 20
• One of the integers = 65

According to the question by using the formula we get,

↦ 65 + x = - 20

↦ x = - 20 - 65

➠ x = - 85

∴ The others integers is - 85.

VERIFICATION :-

⇒ 65 + x = - 20

By putting x = - 85 we get,

⇒ 65 + (- 85) = - 20

⇒ 65 - 85 = - 20

➦ - 20 = - 20

Hence Verified.

Answer 2

Question:

$\sf \: The \: sum \: of \: two \: integers \: is \: -20. If \: one \: of \: them \: is \: 65, find \: the \: other.$

Solution:

$\sf \: Let \: the \: second \: integer \: be \: X \\ \sf \: So,65 + x = - 20 \\ \sf \qquad x = - 20 - 65\\ \sf \qquad \: x = - 85$

$\sf \bold{The \: an other \: integer \: is -80}$

$\bold \red{Celestial} \bold{Centrix}$

Verification:

$\sf \: According \: to \: the \: question, \\ \sf \qquad65 + ( - 80) = - 20 \\ \sf \qquad - 20 = - 20 \\ \sf \qquad \: hence \: proved \:$
