How do you solve  x - 3 > 2?

Sep 2, 2015

x>5

Explanation:

You use this property: an inequality holds if and only if, for any number $x$, the inequality obtained by adding $x$ to both sides holds. This means that we can add (or subtract) any number we want from an inequality. In your case, the good idea is to add $3$ to both sides, since we obtain

$x - 3 + 3 > 2 + 3$

and therefore

$x > 5$
