The sentence "The sum of a number and 81 is greater than the product of 3 and that number" translates to x%2B81%3E3x




x%2B81%3E3x Start with the given inequality.


x%3E3x-81 Subtract 81 from both sides.


x-3x%3E-81 Subtract 3x from both sides.


-2x%3E-81 Combine like terms on the left side.


x%3C%28-81%29%2F%28-2%29 Divide both sides by -2 to isolate x. note: Remember, the inequality sign flips when we divide both sides by a negative number.


x%3C81%2F2 Reduce.

Answer:

So the answer is x%3C81%2F2
