Question 1158602
.
<pre>

It is just couple of weeks I observe your attempts to create a Math problem and/or to ask a Math question.


Since you do not use standard Math notations, and do not use a standard Math language, it is difficult 
to understand the exact meaning of your request.

To define an absolute value equation, you should use the notation like this |x-a| = b.

It is a typical and a simplest equation with absolute value function in the left side.


Such form equation CAN NOT have that set of solutions  x >= 15, as you requested.

In this sense the comment by the tutor @greenestamps is right.


          Nevertheless, there are close forms of the absolute value equation, 

          that DO have this infinite continuous set of solutions  x >= 15.


Such an equation is, for example,  |x-15| - |x+15| = -30.


The Figure below shows the graph of the left side, making the solution EVIDENT.


    {{{graph( 1000, 500, -20, 20, -40, 40,
              abs(x-15) - abs(x+15), -30.2
)}}}


         The solution  of equation  |x-15| - |x+15| = -30. The left side function plot is shown in red.

         The straight line y = -30 is shown in green. 



It is VERY SHOCKING fact to see that an EQUATION may have infinite CONTINUOUS set of solutions.

But an ABSOLUTE VALUE EQUATION CAN (!).

Because it is highly non-linear equation.

When I got this idea and this solution, &nbsp;I was shocked.


I think, &nbsp;you will be shocked too, &nbsp;as well as @greenestamps !



Come again to this forum soon to learn something new (!)
