In the given equation,
![100+4x-4x=](https://img.qammunity.org/2023/formulas/mathematics/college/ty6foe4bib9cd6xodnazwchhs9b3dkyy5v.png)
There are two terms that have the same values but opposite signs. These two terms are 4x and -4x. Because they have opposite signs but the same absolute value, they cancel out,
![100+4x-4x=100](https://img.qammunity.org/2023/formulas/mathematics/college/ol7a347b71zcg6dhfbplkjysnl7dslphn6.png)
Hence, the result is 100.
