(15 x 19 - x - 0,15) : 0,25 = 15 : 0,25
15 x 19 - x - 0,15 = 15
285 - x = 15 + 0,15 = 15,15
x = 285 - 15,15 = 269,85
(15x19-x-0,15):0,25=15:0,25
15x19-x-0,15=15
285-x=15+0,15=15,15

(15 x 9 - X - 0,15 ) : 0, 25 = 15 : 0,25
( 15 x 9 - X - 0,15) : 0,25 = 60
15 x 9 - X - 15 = 60 x 0, 25
15 x 9 - X - 15 = 15
15 x 9 - X= 15 + 15
15 x 9 - X = 30
135 - X = 30
X = 135 - 30
X = 105
ủng hộ mk nha !!!! ^_^

\(2x-\frac{4.36}{0.125}=0.15\times42.9-11.7\times0,25\times0.8\)
\(2x-\frac{872}{25}=\frac{819}{200}\)
\(2x=\frac{819}{200}+\frac{872}{25}=\frac{1559}{40}\)
