$12 (2 \times x)$ $12(2xx x)$

Simplifies to $24 x$ $24x$

Breaking the question down into its component parts

Define a variable: $\to Let x be a variable$ $->" Let "x" be a variable"$

Twelve times the: $\to 12 \times ?$ $->12xx?$
product of: $\to 12 \times (? \times ?)$ $->12xx(?xx?)$

two: $\to 12 \times (2 \times ?)$ $->12xx(2xx?)$

and a number: $\to 12 \times (2 \times x)$ $->12xx(2xx x)$

giving: $12 (2 \times x)$ $12(2xx x)$

In fact this simplifies to $24 x$ $24x$
