A student solved the given equation and justified every step except one. What is the missing reason? A) Associative property of

Anna007 [38]

Given:

The statements and reasons to solve an equation.

To find:

The missing reason.

Solution:

If a, b and c are three real number, then

Associative property of addition : $(a+b)+c=a+(b+c)$

Commutative property of addition : $a+b=b+a$

Multiplicative property of equality : $a=b\Leftrightarrow ca=cb$

Distributive property of multiplication over addition : $a(b+c)=ab+ac$

In the given step, $(x+-3)+3$ is written as $x+(-3+3)$ .

It means, only parenthesis are changed, which is possible by Associative property of addition.

So, the missing reason is Associative property of addition.

Therefore, the correct option is A.
