Answer:
Inverse Property of Addition (Reason C)
Step-by-step explanation:
<u>Given:</u> 3(x – 4) = 33
<u>Prove: </u>x = 15
Statements Reasons
1. 3(x – 4) = 33 Given
2. 3x – 12 = 33 Distributive Property (Reason A)
3. 3x – 12 + 12 = 33 + 12 Addition Property of Equality (Reason B)
4. 3x + 0 = 45 Inverse Property of Addition (Reason C)
5. 3x = 45 Zero Addition Property (Reason D)
6. x = 15 Division Property of Equality
Answer:
x=9
Step-by-step explanation:
- 8.88=4.44x-31.08
- 8.88-4.44x=-31.08
- -4.44x=-31.08-8.88
- -4.44x=-39.96
- x=9(we divided both rquations by -4.44)
X = -5 . I used photomath to solve this so it should be correct, hope this helps
