| deepseekr1 | To simplify the expression \((5x + 3) - 2(2x - 4)\), start by distributing the \(-2\) across the terms in the second parentheses: \[ -2 \times 2x = -4x \quad \text{and} \quad -2 \times (-4) = +8. \] This transforms the expression into: \[ (5x + 3) - 4x + 8. \] Next, combine like terms: - For the \(x\)-terms: \(5x - 4x = x\), - For the constants: \(3 + 8 = 11\). Thus, the simplified expression is \(x + 11\). **Answer:** B. x+11 |

| GPT-4o | To simplify the expression \((5x+3) - 2(2x-4)\), we need to follow these steps: 1. Distribute the \(-2\) through the parentheses: \[ -2(2x-4) = -2 \cdot 2x + (-2) \cdot (-4) = -4x + 8 \] 2. Substitute back into the original expression: \[ (5x + 3) - 4x + 8 \] 3. Combine like terms: \[ 5x - 4x + 3 + 8 = x + 11 \] Therefore, the simplified expression is \(x + 11\). Answer: B |

| minimax | To simplify the expression $(5x+3) - 2(2x-4)$, we distribute the -2 across the terms in the second set of parentheses and then combine like terms: $(5x+3) - 2(2x-4)$ $= 5x + 3 - 4x + 8$ (distribute the -2 to both terms inside the parentheses) $= (5x - 4x) + (3 + 8)$ (rearrange to combine like terms) $= x + 11$ So the simplified form of the expression is $x + 11$. The correct answer is B. x+11. |

| kimi | To simplify the expression \((5x+3) - 2(2x-4)\), you first distribute the \(-2\) across the terms inside the parentheses: \[ (5x+3) - 2(2x-4) = 5x + 3 - 4x + 8 \] Next, combine like terms: \[ 5x - 4x + 3 + 8 = x + 11 \] So the correct answer is: B. x+11 |

| wenxinyiyan | 首先，我们去掉括号，并注意括号前的负号会改变括号内每一项的符号： $(5x+3) - 2(2x-4) = 5x + 3 - 4x + 8$ 接着，我们合并同类项： $5x - 4x = x$ $3 + 8 = 11$ 所以， $(5x+3) - 2(2x-4) = x + 11$ 故答案为：B. $x+11$ |

| zhipu | To simplify the expression \((5x + 3) - 2(2x - 4)\), follow these steps: 1. Distribute the \(-2\) through the parentheses: \[ (5x + 3) - 2(2x - 4) = 5x + 3 - 2 \cdot 2x + 2 \cdot 4 \] 2. Simplify the multiplication: \[ 5x + 3 - 4x + 8 \] 3. Combine like terms: \[ (5x - 4x) + (3 + 8) = x + 11 \] So, the simplified expression is \(x + 11\). The correct answer is: B. x+11 |
