First: solve for "x" and keep it on one side > divide both sides by
-2:
-2x/-2 < 14/-2
Second: when you divide by a negative number, reverse the inequality sign:
x > -7

since you already have the number with the variable which is x, you divide each side by -2.and also reverse the inequality sign which is < to > to solve for x.You reverse the sign because you are dividing the sides with a negative number.
-2x<14
-2x/-2>14/-2
x>7/-1 or x>-7
You can write the answer in a solution set when asked as
Solution Set={x:x>-7} which means x searched that x is greater than -7

X is any positive number or any negative number between -1 and -6. In short, X is any number greater than -7

Divide -2 from both sides:
x>-7
The sign changed because you divided by a negative number.
