-x<= 500-3800+750

Answer 4

What's 500-3800+750?

Okay bingo, now -x≥-2550. But you want the x to be positive, what you do is you change the symbol to ≤. Therefore, x≤2550

Actually the sign will change ONLY when you are multiplying or dividing by a negative number.

Change symbol if you want to change the negative number to positive number when you have the same negative symbol on both sides, that's for addition or deduction.
