Question

Indentify the property transformation or simplification given:7(x-4)+28Step 1 - 7(x-4)+28Step 2: 7x+0Step 7x

Answer 1

Step-by-step explanation

`7(x-4)+28`

Step 1

use distributive property

`\text{remember: a(b+c)=ab+ac}`

then

`\begin{gathered} 7(x-4)+28 \\ 7x-(7)(4)+28 \\ 7x-28+28 \end{gathered}`

Step 2

Add similar terms

`\begin{gathered} 7x-28+28 \\ 7x-0 \end{gathered}`

Step 3

when you have an expression, there is no change if you add cero, or substrate cero, no need to write it, then

`\begin{gathered} 7x-0 \\ 7x \end{gathered}`
