Question

what is the additive inverse of the expression below, where a and b are real numbers ?
2a+b

Answer 1

Answer:

The additive inverse is equal to $-2a-b$

Step-by-step explanation:

we know that

The additive inverse of a number is equal to its opposite ( the sum of a number and its additive inverse is equal to zero)

so

we have

$2a+b$

Multiply by -1

$-1(2a+b)=-2a-b$

therefore

The additive inverse is equal to $-2a-b$
