Given:

The equation is


-5x-16=8

To find:

The error and correct solution.

Solution:

We have,


-5x-16=8

Add 16 on both sides.


-5x-16+16=8+16


-5x=24

Divide both sides by -5.


(-5x)/(-5)=(24)/(-5)


x=-(24)/(5)

Third step is incorrect because he divide the equation by 5 instead of -5.

Therefore, the correct solution is
x=-(24)/(5).
