I'm assuming you want us to solve this inequality for x, since the question wasn't too clear on that.
[tex]x - 35 > 15[/tex]
Add 35 to both sides to remove the "-35" on the left side so we can isolate the x
[tex]x-35+35>15+35[/tex]
[tex]x>50[/tex]
The solution to this inequality is x>50. Let me know if you need any clarifications, thanks!
