確かに、段階的にそれを通過しましょう：
1.最初に括弧を解く：x = 7 + 42（8-2）= 7 + 42（6）= 7 + 42 * 6
2.乗数を数字に分割：x = 7 + 42 * 6 = 7 +（40 + 2） * 6 = 7 + 40 * 6 + 2 * 6
3.乗算：x = 7 + 40 * 6 + 2 * 6 = 7 + 240 + 12
4.合計：x = 7 + 240 + 12 = 247 + 12 = 259
最終結果：x = 259
Sure, let's go through it step by step:
1. Solve parentheses first: X = 7 + 42 (8-2) = 7 + 42 (6) = 7 + 42 * 6
2. Split multiplier into digits: X = 7 + 42 * 6 = 7 + (40 + 2) * 6 = 7 + 40 * 6 + 2 * 6
3. Multiply: X = 7 + 40 * 6 + 2 * 6 = 7 + 240 + 12
4. Sum: X = 7 + 240 + 12 = 247 + 12 = 259
Final result: X = 259
