Answer:
The property used to rewrite the equation is distributive property (option B)
Explanation:
Given:
9n+7-2n = 4(-n+ 5) - 3n
9n+7-2n= -4n+20-3n
To find:
the property used to rewrite the equation
The initial equation:
9n+7-2n = 4(-n+ 5) - 3n
In the 2nd equation, the parenthesis was already removed
To remove the parenthesis, the number outside will be used to multiply the number or expression insides
[tex]\begin{gathered} 9n\text{ + 7 - 2n = 4\lparen-n\rparen + 4\lparen5\rparen - 3n} \\ 9n\text{ + 7 - 2n = -4n + 20 - 3n} \\ \\ The\text{ property where expansion of parenthesis is done this way is called distributive property} \end{gathered}[/tex]
The property used to rewrite the equation is distributive property (option B)
