Question

Sum of two Integers is- 30.if one of them is 15.Find the other integer

Answer 1

Answer:

-45

Step-by-step explanation:

Sum = -30

1st Integer = 15

So, 2nd Integer = -30-15

= -45

Verify : 15+(-45)

= -30

Answer 2

GIVEN:

• Sum of two Integers is- 30
• one of them is 15.

TO FIND:

• What is the other integer ?

SOLUTION:

Let the another integer be 'x'

Here,

• One integer = 15
• Another integer = x

And,

We have given that, the sum of two integers is -30

According to question:-

On putting the given values in the formula, we get

❮ One integer + Another integer = Sum of Integers ❯

$\rm{\dashrightarrow 15 + x = -30 }$

$\rm{\dashrightarrow x = -30 - 15 }$

$\bf{\dashrightarrow x = -45}$

❝ Hence, the another integer is – 45 ❞

VERIFICATION:

➺ $\bf{ 15 + (-45) = -30}$
