Solve the equation.
4|t+9|-5=-19

answer:

4|t+9|-5=19  

Two solutions were found :

t=-3

t=-15

Absolute Value Equation entered :

     4|t+9|-5=19  

Step by step solution :

Step  1  :

Rearrange this Absolute Value Equation

Absolute value equalitiy entered

     4|t+9|-5 = 19  

Another term is moved / added to the right hand side.

     4|t+9| = 24  

Step  2  :

Clear the Absolute Value Bars

Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.

The Absolute Value term is 4|t+9|

For the Negative case we'll use -4(t+9)  

For the Positive case we'll use 4(t+9)  

Step  3  :

Solve the Negative Case

     -4(t+9) = 24  

    Multiply

     -4t-36 = 24  

    Rearrange and Add up

     -4t = 60  

    Divide both sides by 4

     -t = 15  

    Multiply both sides by (-1)

     t = -15  

    Which is the solution for the Negative Case

Step  4  :

Solve the Positive Case

     4(t+9) = 24  

    Multiply

     4t+36 = 24  

    Rearrange and Add up

     4t = -12  

    Divide both sides by 4

     t = -3  

    Which is the solution for the Positive Case

Step  5  :

Wrap up the solution

t=-15

t=-3

Two solutions were found :

t=-3

t=-15
