Question 552653
There previously was an error in the solution, which has now been corrected.

<pre>
You are thinking about equations, not inequalities.  If 4x is less than 4,
which is what 4x < 4 means, then x is less than 1. It cannot be equal to 1.  
In fact x is a variable, and it is not necessarily equal to any one number.
x could be any number less than 1.  It could be {{{1/2}}}, or 0 or 0.7, or -1,
or -46, or -10000000 or -9 or ....  Yes it could be -1, but certainly not
necessarily.

There is no one number that x can only be, because x is a variable, and can
vary its value to any number less than 1.

We make a number line, and shade the part x can be. It cannot be 1,
so we put an open circle there

<==================o------------------
-5 -4 -3 -2 -1  0  1  2  3  4  5

That is the graph of the solution set of the inequality 4x < 4 or x < 1
