The word "is" in this kind of problem typically means "=", so we know that something =-8. Since we're finding the number, we should start with the closest thing in the phrase given to that number. In this case, it's 3/4x. Finally, since we have the "14 less than", we need to add that in. Your answer is:
3/4x-14=-8. Now we can just solve! +14 +14
3/4x=6. *4/3 *4/3
x=8. <em> </em> <em><u>Don't forget to rate this answer the </u><u>Brainliest</u><u>!</u></em>
