Question

Explain which property of equality is used to arrive at the conclusion for the following if x=4 then x+12=16

Answer 1

The property is addition property

Explanation:

The addition property of equality tells us that adding the same number to each side of an equation gives us an equivalent equation

For instance

if a−b = c, then a−b+b = c+b, or a=c+b

The same goes to the given problem too if x=4 then x+12=16

Answer 2

Hello!

The answer is: the addition property

Why?

Addition property states that:

if:
`a=b`

Then,

`a+c=b+c`

So,

Let:

`a=x=4\\b=4\\c=12`

So,

`x+12=b+12\\4+12=4+12\\16=16`

Have a nice day!
