The correct Answer is:
To solve the problem step by step, we need to first rewrite the expression according to the information provided: 1. **Original Expression**: 6 + 7 x 3 - 8 ÷ 20 2. **Substitutions**: - Replace '+' with 'x' (multiplication) - Replace '-' with '÷' (division) - Replace '÷' with '-' (subtraction) 3. **Rewritten Expression**: - 6 x 7 x 3 ÷ 8 - 20 Now, we will solve the expression step by step: ### Step 1: Calculate 6 x 7 - \( 6 x 7 = 42 \) ### Step 2: Multiply the result by 3 - \( 42 x 3 = 126 \) ### Step 3: Divide the result by 8 - \( 126 ÷ 8 = 15.75 \) ### Step 4: Subtract 20 from the result - \( 15.75 - 20 = -4.25 \) ### Final Answer: - The final result is **-4.25**.
