Will give branilets how many solutions does the equation 4y − 4y − 12 = 14 − 2 have? one zero two many

No matter what number you substitute for y, this equation will be untrue.

It has zero solutions.

When simplifying the equation 4y-4y-12=14-2, first you combine like terms.
4y-4y-12=14-2
0y-12=12
Then the y cancels out because of the 0 and you get -12=12.
Since -12=12 is false, this means that this equation has zero solutions. 
Hope this helps!
