150 - 5x . 18 = 118
5x . 18 = 150-118
5x . 18 = 32
5x = 32 : 18
5x = 16/9
x = 16/9 : 5
x = 16/45
\(150-5x\times18=118\\ 5x\times18=150-118\\ 5x\times18=32\\ 5x=32:18\\ 5x=\dfrac{16}{9}\\ x=\dfrac{16}{9}:5\\ x=\dfrac{16}{45}\)
Vậy \(x=\dfrac{16}{45}\)
150 - 5x . 18 = 118
5x . 18 = 150-118
5x . 18 = 32
5x = 32 : 18
5x = 16/9
x = 16/9 : 5
x = 16/45
