Answer:
Step-by-step explanation:
<u>Simplify the expression:</u>
- 4(3b) – 2(3b + 1) =
- 12b - 6b - 2 =
- 6b - 2
Correct choice is D
Yo it is x,y the one on the bottom is x the one on the top is y
Given:

To find:
The missing value.
Solution:
Let x be the missing value.
We have,


Subtract
from both sides.




Multiplying both sides by 5, we get

So, the missing value is 3.
Therefore, the correct option is C.
You can't solvd monomials because they are just 1 term multiplication :
example: 2a , or 14
