Step-by-step explanation:

Given:

Sam solved the following problem:

-4x + 5 > 29

-4x + 5 - 5 > 29 - 5

-4x > -24                ......Mistake 1

-4x/-4 > -24/-4       ......Mistake 2

x > 6                      ......Mistake 3

The Correct Answer is

-4x + 5 > 29

Subtract 5 in both the side

-4x + 5 - 5 > 29 - 5

Then we get,

-4x > 24  

Divide both the side by -4 we get          

[tex]\dfrac{-4x}{-4}>\dfrac{24}{-4}[/tex]

Then we get,

[tex]x > -6[/tex]
