How many solutions does the equation 4y − 4y − 12 = 14 − 2 have? one none two infinite

When simplifying the equation 4y-4y-12=14-2, first you combine like terms.4y-4y-12=14-20y-12=12Then 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!

I’m not absolutely sure but i think it’s 7x6x5x4x3x2=5040 because as the first character you can take any of the 7 given then you are left with 5 then 6 then 4 etc.
