Question

Part A: Solve the equation 4(x + 5) = 9x + 4x − 34, and show your work. (5 points)

Part B: Use this list of properties to justify each step of your math work. Justifications may be used more than once if needed. (5 points)

Answer 1

missing list for part B)

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

Answer 2

for proofs, you typically start with "given" and copy down the information you are already given

so you would start with:
Given: 4(x + 5) = 9x + 4x − 34

from there, you can start performing operations, justifying each step with one of the properties from the list.

for example, you can distribute the 4 from 4(x+5) using the distributive property of equality.

try solving it, I'll help you out if you get stuck.

Answer 3

so basically it would be x+6 right

Answer 4

yes, that's the solution, but keep in mind the problem is asking for all steps

Answer 5

oh so i would have to put how i got it

Answer 6

yes

Answer 7

oh

Answer 8

4(x + 5) = 9x + 4x − 34
4x+20=13x-34
20+34=13x-4x
54=9x
6=x
