Remark
Thank you for editing your question. Very few people do and those of answering don't really like reporting incomplete questions (or I don't).
You could write it like this.
Solve[tex] \dfrac{x}{7} > 800 [/tex] Multiply both sides by 7
x > 800 * 7
x > 5600 That would make the inequality equal to 800 if x = 5600.
You need to go just 1 step further. Try 5607. When you divide that by 7, you get 5607/7 = 801 which is 1 bigger than 800.
