5 - 2 * < 7

Question

`5 - 2 * < 7`

Answer 1

To solve 5 - 2x < 7, we need to get x on one side of the inequality. Then, we want to get a singular x which will be our answer. We start by switching the side of the terms with numbers that are on the same side of the term with x.

5 - 2x < 7

5 - 5 - 2x < 7 - 5

-2x < 2

Now, we need to divide each side by -2. This will get us a singular x. But, the trick here is to switch the direction of the inequality symbol. That is the rule when dividing by a negative number.

-2/-2x > 2/-2

x > -1
