Write 21 in the blank for no values of x, write -4 in the blank for all the values of x and write -4x in the blank for one value of x.
Given-
Equation given in the problem is,
[tex]4x-4=4x+[/tex]___
In the given equation there is one variable [tex]x[/tex] which is unknown.
- Put 21 in the blank to make equation true for the no values of x, we get,
[tex]4x-4=4x+23[/tex]
[tex]4x-4x=21+4[/tex]
[tex]0=25[/tex]
It will work for no value of x.
- Put -4 in the blank to make equation true for the no values of x, we get,
[tex]4x-4=4x+(-4)[/tex]
It will work for any odd value of [tex]x[/tex].
- Put -4x in the blank to make equation true for the one values of x, we get,
[tex]4x-4=4x-4x[/tex]
[tex]4x-4=0[/tex]
[tex]x=1[/tex]
Here we get one single solution.
Hence Write 21 in the blank for no values of x, write -4 for all the values of x and write -4x in the blank for one value of x.
