\(4 \cdot x\) \(x + 27\) \(x - 27\) \(100 - x\) \(x + x\) \(3 \cdot x\)
45 \(4 \cdot 45 = 180\) \(45 + 27 = 72\) \(45 - 27 = 18\) \(100 - 45 = 55\) \(45 + 45 = 90\) \(3 \cdot 45 = 135\)
61 \(4 \cdot 61 = 244\) \(61 + 27 = 88\) \(61 - 27 = 34\) \(100 - 61 = 39\) \(61 + 61 = 122\) \(3 \cdot 61 = 183\)
