    Answer:

    3x-10<5\\x<5

    Step-by-step explanation:

    Let x be equal to the number.

    We can use what the question gives us to directly form a mathematical statement. When you multiply it by 3 (3x) and then subtract 10 (3x-10) you will get a number less than 5 (<5). Using this, our mathematical statement would look like this:

    3x-10<5

    To find the range of possible values, we must solve the inequality and isolate x.

    3x-10<5

    Add 10 to both sides

    3x-10+10<5+10\\3x<15

    Divide both sides by 3

    \frac{3x}{3}<\frac{15}{3}\\x<5

    I hope this helps!
