Answer 1

→Question: The sum of two rational numbers is -16. If one of the number is -4. Find the other number?

→Answer:

• let the 2 numbers be x and y
• according to the question:
• x+y = -16

→Where:

• x = -4

→To find:

• y = ?

→Solution:

• x+y = -16
• -4+y = -16
• y = -16+4
• y = -12

→Verify:

• x+y = -16
• -4+-12 = -16
• -16 = -16
• ∴L.H.S=R.H.S
• The other number is -12

Answer 2

Given :-

• Sum of two rational numbers is -16.
• One number is -4.

⠀

To find :-

• Another rational number.

⠀

Solution :-

• Let the another rational number be x.

⠀

Now, accordinga to the question.

Sum of two rational numbers is -16.

⠀

→ x + (-4) = -16

⠀

→ x - 4 = -16

⠀

→ x = -16 + 4

⠀

→ x = -12

⠀

Therefore,

• The other rational number is -12.
