9 • ( x - 3 ) = 10^3 - 1000

To solve the equation \( 9 \cdot (x - 3) = 10^3 - 1000 \), we will first simplify the right side:

\[ 10^3 = 1000 \]

Now substitute this into the equation:

\[ 9 \cdot (x - 3) = 1000 - 1000 \]

This simplifies to:

\[ 9 \cdot (x - 3) = 0 \]

Next, divide both sides by 9:

\[ x - 3 = 0 \]

Now add 3 to both sides:

\[ x = 3 \]

Thus, the solution is:

\[ \boxed{3} \]
