Question

`x + 3/4 = 5/3`

`x - 2/3 = 7/2`

Answer 1

bài lớp 4 chứ nhỉ 

x= 11/12

x= 7/3

Answer 2

\(x=\frac{11}{12}\)

 

\(x=\frac{7}{3}\)

Answer 3

x = 11/12

x= 25/6

Answer 4

X = 5/3 - 3/4 

X = 11/12

 

X = 7/2 + 2/3

X = 25/6

Answer 5

\(x+\dfrac{3}{4}=\dfrac{5}{3}\)

\(x=\dfrac{5}{3}-\dfrac{3}{4}\)

\(x=\dfrac{20}{12}-\dfrac{9}{12}\)

\(x=\dfrac{11}{12}\)

 

\(x-\dfrac{2}{3}=\dfrac{7}{2}\)

\(x=\dfrac{7}{2}+\dfrac{2}{3}\)

\(x=\dfrac{21}{6}+\dfrac{4}{6}\)

\(x=\dfrac{25}{6}\)

Answer 6

A, x = 11/12

B, x = 25/6

Answer 7

\(x+\) \(\dfrac{3}{4}\) \(=\) \(\dfrac{5}{3}\) 

\(x=\) \(\dfrac{5}{3}\) - \(\dfrac{3}{4}\) 

\(x=\) \(\dfrac{11}{12}\) 

____________

\(x-\) \(\dfrac{2}{3}\) \(=\) \(\dfrac{7}{2}\) 

\(x=\) \(\dfrac{7}{2}\) - \(\dfrac{2}{3}\) 

\(x=\) \(\dfrac{17}{6}\)

Answer 8

\(x+\dfrac{3}{4}=\dfrac{5}{3}\)                         \(x-\dfrac{2}{3}=\dfrac{7}{2}\)

\(x\)         \(=\dfrac{5}{3}-\dfrac{3}{4}\)                 \(x\)         \(=\dfrac{7}{2}+\dfrac{2}{3}\)

\(x\)         \(=\dfrac{11}{12}\)                       \(x\)         \(=\dfrac{25}{6}\)

Answer 9

\(x \) + \(\dfrac{3}{4}\) = \(\dfrac{5}{3}\)                                   \(x\) - \(\dfrac{2}{3}\) = \(\dfrac{7}{2}\)
\(x\)        = \(\dfrac{5}{3}\) - \(\dfrac{3}{4}\)                             \(x\)        = \(\dfrac{7}{2}\) + \(\dfrac{2}{3}\)
\(x\)        = \(\dfrac{11}{12}\)                                  \(x\)       = \(\dfrac{25}{6}\)

Answer 10

\(x+\dfrac{3}{4}=\dfrac{5}{3}\)

\(x=\dfrac{5}{3}-\dfrac{3}{4}\)

\(x=\dfrac{11}{12}\)

Answer 11

\(x-\dfrac{2}{3}=\dfrac{7}{2}\)

\(x=\dfrac{7}{2}+\dfrac{2}{3}\)

\(x=\dfrac{7}{3}\)
