Ha Long Bay is one of the most beautiful natural wonders of Vietnam. Located in Quang Ninh Province, the bay is famous for its emerald-green water and thousands of limestone islands rising majestically from the sea. Visitors can explore stunning caves, hidden beaches, and peaceful fishing villages scattered throughout the bay. The scenery looks especially magical at sunrise and sunset, when the sunlight reflects off the water like a painting. Ha Long Bay is not only a popular tourist destination but also a UNESCO World Heritage Site, recognized for its unique geological value. For many people, a trip to Ha Long Bay is an unforgettable experience filled with beauty and tranquility.

2(\(x-33\)) - 3.(\(x-43\)) = 96 - 115

2\(x\) - 66 - 3\(x\) + 129 = 96 - 115

2\(x-3x\) = 96 - 115 + 66 - 129

- \(x\) = - 19 + 66 - 129

- \(x\) = 47- 129

- \(x\) = -82

\(x=-82:\left(-1\right)\)

\(x=-\) 82

Vậy \(x=-82\)

2(\(x-33\)) - 3.(\(x-43\)) = 96 - 115

2\(x\) - 66 - 3\(x\) + 129 = 96 - 115

2\(x-3x\) = 96 - 115 + 66 - 129

- \(x\) = - 19 + 66 - 129

- \(x\) = 47- 129

- \(x\) = -82

\(x=-82:\left(-1\right)\)

\(x=-\) 82

Vậy \(x=-82\)

2(x-33)-3.(x-32)=96-115

2x-66-3x+129=-19
