|5x|+5=45<br><br> can you explain this absloute value equation <br> i have a midterm
Ymorist [56]
So first, you get the absolute value to one side:
|5x|+5=45\\&#10;|5x|=40

Next, set up two equations; One where the value inside the absolute value lines is positive, and another where it is negative, and solve both for the variable:
|5x|=40\\5x=40\\x=\frac{40}{5}=8\\\\-5x=40\\x=\frac{40}{-5}=-8

Your answers are 8 and -8, or +-8.
