Answer: What question? wdym?
Step-by-step explanation:
Answer:
<u>Yes</u>
- (2 · x) + (2 · 7) = 36
- x + 7 = 18
- 2x + 14 = 36
<u>No</u>
- 2x + 7 = 36
- 2(x + 7) = 72
- x + 14 = 36
Step-by-step explanation:
It is appropriate to eliminate parentheses as a first step. This can be done using the distributive property, resulting in either of ...
- 2x +2·7 = 36
- 2x +14 = 36 . . . . . 2·7 evaluated mentally
or by dividing the equation by the factor outside parentheses, resulting in ...
___
Any of the equations other than these represent violations of the equal sign. Something has been done to one side of the equation without the same thing being done to the other side.

The answer to this question is 7 4/9
to find this you first have to find the LCM (in this case it is 9) then you have to figure what you multiplied by to get to your LCM (9) whatever you do to the bottom you have to do to the top and that is how you end up with your numerator (the top number in a fraction) usually if you have the same denominators (the bottom number in a fraction) you can +/- like normal. sometimes though you can't (like this case) because you can't take a bigger number away from a smaller one.
