a ) P = 1496 : ( 213 - 145 ) + 237

b ) 373 = 1496 : ( 213 - x ) + 237

Bạn ơi k giùm mk nha! ^_^
p = 1496: (213 : \(x\)) + 237 khi \(x=145\)
khi \(x=145\) ta có: p = 1496: (213 : 145) + 237
p = 1496 : \(\dfrac{213}{145}\) + 237
p = 1496 \(\times\) \(\dfrac{145}{213}\) +
p = \(\dfrac{216920}{213}\) + \(\dfrac{50481}{213}\)
p = \(\dfrac{2674101}{213}\)
Vậy p = \(\dfrac{267401}{213}\)
b; P = 1496 : (213 : \(x\)) + 237 tìm \(x\) khi p = 375
1496 : (213 : \(x\)) + 237 = 375
1496 : (213 : \(x\)) = 375 - 237
1496 : (213 : \(x\)) = 138
213 : \(x\) = 1496 : 138
213 : \(x\) = \(\dfrac{748}{69}\)
\(x\) = 213 : \(\dfrac{748}{69}\)
\(x\) = \(\dfrac{14697}{748}\)
y x 145 + y x 355 = 965000
y x ( 145 + 355 ) = 965000
y x 500 = 965000
y = 965000 : 500
y = 1930
k mk nha
y x 145 + y x 355 = 965000
y x (145 + 355) = 965000
y x 500 = 965000
y = 965000 : 500
y = 1930
(y - 22) : 213 = 206
y - 22 = 206 x 216
y - 22 = 43878
y = 43878 + 22
y = 43900
