WHICH INEQUILITY IS EQUIVALENT TO X-4<9

frez [133]

-------------------------------------------------------------------------------------------------------------

Answer: $\textsf{x} < \textsf{13}$

-------------------------------------------------------------------------------------------------------------

Given: $\textsf{x - 4} < \textsf{9}$

Find: $\textsf{The simplified inequality}$

Solution: In order to simplify the inequality we can simply add 4 to both sides which would isolate x.

<u>Add 4 to both sides</u>

$\textsf{x - 4 + 4} < \textsf{9 + 4}$

$\textsf{x} < \textsf{9 + 4}$

$\textsf{x} < \textsf{13}$

Therefore, an inequality that would be equivalent to the one that was provided in the problem statement is x < 13.
