Answer 2

Given:

Sum of two Integer is- 30

One of them is 15.

Find:

The other integer

Solutions:

Let the another integer be 'x'.

• One integer = 15
• Another integer = x

And,

We have that,

The sum of two integers is -30.

One integer + Another integer = Sum of Integers

=> 15 + x = -30

=> x = -30 - 15

=> x = -45

Hence, the another integer is – 45.

Verification:

=> 15 + (-45) = -30

=> 15 - 45 = -30

=> -30 = -30

Hence Verify.

Important Information:

• Adding two positive integers will always result in a positive integer.
• Adding two negative integers will always result in a negative integer.
