Question

nine less than the product of a number and 4

Answer 1

Let the unknown number be x.

The question says "9 less than the product of a number and 4".

The product of the unknown number (x) and 4 is:

$4\times x=4x$

Now, we are told that 9 is less than this product. This also implies that the product is greater than 9.

So we can write:

$\begin{gathered} 9<4x \\ or \\ 4x>9 \end{gathered}$
