Nine less than the product of 2 and a number is 4

Answer 1

Let x be a number. The equation is:

2x - 9 = 4

You can solve if needed.

Answer 2

I believe "less than" means inequality not subtraction.

Answer 3

L's equation is correct

2x=13
x = 6.5

twice the number is 13
What is 9 less than that ?

Answer 4

L is right.

Answer 5

9+4=13
13/2=6.5
So the answer is 6.5
