Thank you so much :D

Answer 3

you only change symbols when dividing by a negative number..but when adding and subtracting both sides no change

Answer 4

oh ok :D

Answer 5

I'll have to remember that :)

Answer 6

the way i remember it is this way...for example i have \[-x \le 4\] i'll make x positiveby adding x to both sides so i have \[0 \le 4 + x\] now i let x be alone by subtracting 4 from both sides \[-4 \le x\] in this method...it's the position of the left side and right side that interchanges and the symbol remains the same
