\(x+\frac{145}{245}=\frac{52}{70}\)

\(\Leftrightarrow x+\frac{29}{49}=\frac{26}{35}\)

\(x=\frac{26}{35}-\frac{29}{49}\)

\(x=\frac{182}{245}-\frac{145}{245}\)

\(x=\frac{37}{245}\)

x+145/245 =52/70 

⇔x+29/49 =26/35 

x=26/35 −294/9 

x=182/245 −145/245 

x=37/245 

x=52/70-145/245

x=37/245

Duyệt đi

X + 145/245 = 52/70

X                = 52/70 - 145/245

X                = ??? MÁY TÍNH

X + 145/245 = 52/70

x                =52/70 -145/245

x               =........................

\(x+\frac{145}{245}=\frac{52}{70}\)

\(x=\frac{52}{70}-\frac{145}{245}\)

\(x=\frac{37}{245}\)

x = 52/70 - 145/245

x = 37/245

\(x+\frac{145}{245}=\frac{52}{70}\)

               \(x=\frac{52}{70}-\frac{145}{245}\)

               \(x=\frac{37}{245}\)

Vậy \(x=\frac{37}{245}\)

x+145/245=52/70

x=52/70-145/245

x=181/1764

1. x = 405

2. y = 1/3

3. x = 37/245

4. 0

1= 405

2 = 67/201

3 = 37/245

4 = 0

x=52/70-145/245

x=37/245

x=52/70-145/245

x=37/245

x + 145/245 = 52/70

x                = 52/70 - 145/245

x                = 26/35 - 29/49

x                = 37/245

k cho mk nha 

x=37/245

đó chính là 37 đó

x + 145 /245 = 52/70

245 : 70 = 3,5

52 x 3,5 182

x + 145=182

x         = 182 - 145

x         = 37

a, X = 273

b, X = 156

c, X = 4

d, X =  505

e, X = \(\frac{37}{245}\)
