anafrauca: what number can replaced the (x) that is equal to 0 (zero) in this equation 4x-1=0
I think that you just want to solve
4x - 1 = 0
You have to think about what needs to be done to get x by itself on the left hand side. Don't think about the right hand side.
First you need to get rid of -1, what is the opposite of taking 1 away? The opposite would be to add 1 on.
So add 1 to the left hand side. However if you add one to the left then you have to add 1 to the right or the the equation won't be equal anymore.
that is
4x - 1 +1 = 0+1
4x = 1
x multiplied by 4 = 1
now what do you have to get rid ot the 4, what is the opposit of multiplying by 4? Dividing by 4 is the answer.
so divide BOTH sides by 4 and you will have your answer
+118723
