Question

I need the answers pls!

Answer 1

Given:

The equation is

`(2a-4)/(3)=8`

To find:

The reason for second step.

Solution:

We have,

`(2a-4)/(3)=8`

Using multiplication property of equality, multiply both sides by 3.

`3\left((2a-4)/(3)\right)=3(8)`

`2a-4=24`

Using addition property of equality, add 4 on both sides.

`2a-4+4=24+4`

`2a=28`

Using division property of equality, divide both sides by 2.

`(2a)/(2)=(28)/(2)`

`a=14`

So, the reason for second step is multiplication property (=).

Therefore, the correct option is D.
