Step-by-step explanation:
(-5)-(7) can easily be called -5-7 when all the brackets are taken away
-5-7= -12
Answer:
You can use the additive inverse to solve for x
Step-by-step explanation:
The additive inverse acquits you to change two things: the negative sign and -7
Therefore, after implementing the additive inverse, here's your expression: -5 + -7. Remeber, the rule for adding negative rational numbers: the sum of 2 negative numbers will be negative. Therefore, simply add 7 + 5 to get 12. Remebering out rule of adding negative rational numbers, you should receive -12 as your answer.
