Question 1203395
.
ax + b = c solve for x
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
Three cases may happen:


    (a) no solutions;

    (b) infinitely many solutions;

    (c) one and only one solution.


Case (a) happens when a= 0, b =/= c.

Case (b) happens when a= 0, b = c.

Case (c) happens when a =/= 0,  while b and c may have arbitrary values.


In this case,  x = {{{(c-b)/a}}} is the unique solution.
