1. The problem is to simplify the expression $8 \times 9 / 5 + 1 \times x$. 2. According to the order of operations (PEMDAS/BODMAS), multiplication and division are performed from left to right before addition. 3. First, calculate $8 \times 9$: $$8 \times 9 = 72$$ 4. Next, divide the result by 5: $$\frac{72}{5}$$ 5. The expression now is: $$\frac{72}{5} + 1 \times x$$ 6. Since $1 \times x = x$, the expression simplifies to: $$\frac{72}{5} + x$$ 7. Therefore, the simplified expression is: $$\frac{72}{5} + x$$
