What is the answer to y - 4 equals 0?

Answer 1

so you first want to wright down the equation (it helps later in math) like this...

y - 4 = 0

then you want to isolate "y" so to cancel out the -4 you have to make it 0. however if you add 4 to the equation then you have to do the same on the other side of the equation such as...

y - 4 + 4 = 0 + 4

From there it is simple arithmetic...

Y = 4

and there is your answer
