Which of the following expressions is equivalent to a+(– b)? Select all that apply.

Setler79 [48]

Answer: first option.

Step-by-step explanation:

Given the expression:

$a+(- b)$

You need to remember the multiplication of signs:

$(+)(+)=+\\(-)(-)=+\\(-)(+)=-$

Then, you know that:

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

So, an equivalent expression must have $a$ and $-b$ . Let's check the expressions provided in the options:

$(- b ) + a=-b+a \\\\b + (-a)=b-a \\\\(-a ) + b=-a+b$

You can observe that the equativalent expression is:

$(- b ) + a$
