8 14 – 2(x + 8) = 5x – (3x – 34); Prove: r = -9 Statements The Correct Answer and Explanation is: Let’s solve the equation step-by-step: Given:8⋅14−2(x+8)=5x−(3x−34)8 \cdot 14 – 2(x + 8) = 5x – (3x – 34)8⋅14−2(x+8)=5x−(3x−34) Step 1: Simplify both sides. First, simplify the left-hand side:8⋅14=1128 \cdot 14 = 1128⋅14=112−2(x+8)=−2x−16-2(x
