Write a C program, called linear solver.c, that solves single-variable linear equations. The pro-
gram should prompt the user to enter a linear equation of the form
aY + b = c
where a, b, and c are real numbers of type double. The program should then output the value of Y
that solves the equation, if such a value exists (see the note about verifying that a in nonzero). If the
input provided by the user is not valid, the program should terminate with an appropriate error message.
