Part A: Solve the equation 4(x + 5) = 9x + 4x − 34, and show your work. Part B: Use this list of properties to justify each step of your math work.
Justifications may be used more than once if needed.

Distributive Property
Subtraction Property of Equality
Combine Like Terms
Multiplication Property of Equality
Division Property of Equality
Given
Addition Property of Equality

this sounds about right!

Step-by-step explanation:

4(x+5)=9x+4x-34 is distributive property

4x+20=9x+4x-34 is subtraction property of equality

4x+20=13x-34 is combine like terms

and the rest sounds great!

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
