Answer 2

Solution:-

━━━━━━━━━━━━━━━━━━━━━━━━━━

$:\implies$ Here the question has given us the sum of 2 integers that is -25. The question has also given us one of the integer that is 20. Now, the question has asked us to find the other integer. So to find the other integer follow the steps shown below.

ANSWER:-

⇒ 2nd Integer is -45.. Option C is correct.

GIVEN:-

◦ Sum of 2 integers = -25

◦ 1st integer = 20

TO FIND:-

⟶ 2nd integer = ?

FORMULA:-

• 1st Integer + 2nd Integer = Total

SOLVING STEP BY STEP:-

◦ Sum of 2 integers = -25

◦ 1st integer = 20

◦ 1st Integer + 2nd Integer = Total

• APPLYING THE FORMULA:-

» Let the 2nd integer be x.

» 20 + x = -25

» Taking 20 to R.H.S.

» x = -25 -20

» x = -45

Thus, we got the answer. The 2nd integer is -45. So, option C is correct.

VERIFICATION:-

⚩ 1st Integer = 20

⚩ 2nd Integer = -45

⚩ 20 + (-45) [ (+) + (-) = (-) ]

⚩ 20 - 45

⚩ 20 - 45 = -25

⚩ -25

Hence, verified.
