Answer 1

Hello!

Answer:

`\Large \boxed{\sf -2}`

Explanation:

→ We want to simplify:

`\sf 7 + (-9)`

→ We know:

To add two relative numbers with opposite signs, we subtract the smaller distance to zero from the larger one and take the sign of the one with the greater distance to zero.

→ So our expression is equal to:

`\sf 7 - 9`

→ Simplify the expression:

`\boxed{\sf -2}`

Conclusion:

The expression 7 + (-9) is equal to -2. So the correct answer is -2.
