Hi there! :)
Answer:
x>24
*The answer must have a positive sign and greater than symbol sign.*
Explanation:
First, you switch sides.
![x+18>42](https://img.qammunity.org/2019/formulas/mathematics/high-school/ic2mcik0rrwuoowppbljpqifldlhygee9w.png)
Then, you subtract by 18 from both sides of an equation.
![x+18-18>42-18](https://img.qammunity.org/2019/formulas/mathematics/high-school/9a09v8b7lzdoheom0b08r83lxm8qpx5e45.png)
Finally, you subtract by the numbers from left to right.
![42-18=24](https://img.qammunity.org/2019/formulas/mathematics/high-school/p04sxdwzduojdohsda6bdqpjv2th17xf6b.png)
Final answer is x>24
I hope this helps you!
Have a nice day! :)
