1. Stating the problem: Simplify the expression $X2 - 2x2$. 2. Understanding the expression: It looks like the expression involves variables and numbers. Assuming $X2$ means $X \times 2$ and $2x2$ means $2 \times 2$. 3. Write the expression clearly: $$2X - 2 \times 2$$ 4. Calculate the multiplication: $$2X - 4$$ 5. Final simplified expression: $$2X - 4$$ This is the simplified form of the given expression.
