Question

Which equation represents the sentence?

Six less than 3 times a number is 39.

3 – 6x = 39
3x – 6 = 39
3(x – 6) = 39
6 – 3x = 39

Answer 1

"six less than" means you are subtracting 6 from something. "3 times a number" means you are multiplying 3 times an unknown number x. So we have 3x-6=39. The word "is" means "equals".

Answer 2

6 – 3x = 39
