Chapter P, Problem 46RE
Solution

The solution of the given equation.

  x=12, and x=−1

Given information:

The equation given is:

  4x+1=3 .

Formula used:

  • For any x :

  x=x if x is positive−x if x is negative

Calculation:

In order to solve the given equation:

  4x+1=3

Use for any x :

  x=x if x is positive−x if x is negative

Note that 4x+1 is positive for

  4x+1≥04x≥−1x≥−14

And 4x+1 is negative for

  x≤−14

Thus,

  4x+1=4x+1 if x≥−14−4x+1 if x<−14

Thus the solution of original equation can be find as:

  for x≥−144x+1=34x=3−1x=142x=12And for x<−14−4x+1=34x+1=−34x=−3−1x=14−4x=−1

Thus, combining the solution above for the solution of given equation is:

  x=12, and x=−1
