Which equation is equivalent to 5x-2(7x+1)=14x
a. -9x-2=14x
b. -9x+1=14x
c. -9x+2=14x
d. 12x-1=14x

To know if which equation is equivalent to 5x-2(7x+1)=14x, what we are going to do is to simplify it with its similar terms.
Firstly, we multiply -2 by 7x + 1 and we get -14x -2. 
Now, it will look like this.
5x-14x-2 = 14x
Then, -9x-2 = 14x. 
Therefore, the correct answer would be option A. Hope this answer helps. 

29. because you will divide each number of months by 12 to find the number of years. which would mean, 5, 12.5, 16, 45, 50, 72.5. which is crazy. anyhow, i think you find the median in the middle. and yea hope your test goes good
