Answer 1

The value of M in the equation -12 + 5 = M is -7.

Step-by-step explanation:

The value of M in the equation -12 + 5 = M can be found by simply adding -12 and 5. The addition of a negative number and a positive number involves subtracting the smaller number from the larger one and keeping the sign of the larger absolute value number.

So, -12 + 5 is the same as 5 - 12, which equals -7. Therefore, the value of M is -7.
