How do you solve x + 5 < 3 ?

Jul 31, 2016

$x < - 2$

Explanation:

Treat an inequality in the same way as an equation, unless you multiply or divide by a negative value, in which case the inequality sign changes around.

$x + 5 < 3$

$x < 3 - 5$

$x < - 2$

To give a more detailed answer, we would need to know what type of number we are dealing with.

Real numbers? Integers? Natural numbers? (which would have no solution in this case)

All we DO know is that $x$ is a value less than -2.#
