Question

Tìm x :

a) x - 7/12 = 1/3                                        b) x + 31/10 = 14,5 + 12/10

Answer 1

A, 11/12

B, 12,6

Answer 2

a,

x- 7/12 = 1/3

x = 1/3 + 7/12

x = 11/12

b,

x + 31/10 = 14,5

x = 14,5 - 31/10

x = 57/5

Answer 3

\(a,\\ x=\dfrac{1}{3}+\dfrac{7}{12}=\dfrac{11}{12}\\ b,\\ x+\dfrac{31}{10}=\dfrac{157}{10}\\ x=\dfrac{157}{10}-\dfrac{31}{10}=\dfrac{63}{5}\)

Answer 4

\(a,x=\dfrac{1}{3}+\dfrac{7}{12}\)                     \(b,x+\dfrac{31}{10}=\dfrac{157}{10}\)

\(x=\dfrac{4}{12}+\dfrac{7}{12}=\dfrac{11}{12}\)              \(x=\dfrac{157}{10}-\dfrac{31}{10}=\dfrac{126}{10}=\dfrac{63}{5}\)

Answer 5

a) x - 7/12 = 1/3

    x            = 1/3 + 7/12

    x            =     11/12                                      

b) x + 31/10 = 14,5 + 12/10

     x + 31/10 =    157/10

     x               = 157/10 - 31/10

     x               =      126/10

Answer 6

a) x = 1/3 + 7/12

x = 11/12

vậy x =...

b) x + 31/10 = 157/10

x = 157/10 - 31/10

x - 63/5

vậy x =...
