Which equation is equivalent to 5x-2(7x+1)=14x

Answer 1

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.
