Answer:
B. Multiply 6 by 3
Step-by-step explanation:
Do the opposite order of what Hannah did. The last step that she did was divide by 3, so you would multiply the result (6) with 3:
B. Multiply 6 by 3
Your step by step for getting the number Hannah started with:
First, multiply 6 with 3:
6 x 3 = 18
Next, subtract 4:
18 - 4 = 14
Next, divide by 2:
14/2 = 7
Hannah started with the number 7.

Answer:
yesssssssssssssss do itttttttt
Answer:
14 - 9x + 12 + x
This is an <em>expression </em>(not an equation), therefore it can't be solved.
<u>Factor the expression</u>
Collect like terms:
⇒ 14 + 12 - 9x + x
Combine like terms:
⇒ -8x + 26
Find the highest common factor of 26 and 8
- Factors of 26: 1, 2, 13, 26
- Factors of 8: 1, 2, 4, 8
Therefore, the highest common factor is 2
Factor out -2 from -8x + 26:
⇒ -2(4x + 13)
Alternatively, factor out 2 from 26 - 8x:
⇒ 2(13 - 4x)
