In order to find which one is or isn't, you need to solve for the value of 'x'.
2x + 15 = 35
2x = 20
x = 10
Substitute x =10, into equation. If each side are not the same (i.e. 0=2), then that's the equation that is not equivalent,
Answer is B
Double check this. Chur! :)
Hope this makes sense.
Answer: 
Step-by-step explanation:
Given
Coordinates of Point A is
i.e. Point A is 3 units to the left and 4 units below x-axis
From figure, we can write

9.82-9.71=.11
.11x100 divided by 9.82 = 1.12%

and you plug that in your calculator to get about -0.27465307216702742285.
