Question

Tìm x:

a)15/6 + x = 19/3

b) x-7/8 = 1/2

Answer 1

`a, x = 19/3 - 5/2`

`x= 23/6`

`b, x = 1/2 + 7/8`

`x = 11/8`

Answer 2

\(a,x=\dfrac{19}{3}-\dfrac{15}{6}\\ x=\dfrac{19.2-15}{6}\\ x=\dfrac{23}{6}\\ b,x=\dfrac{1}{2}+\dfrac{7}{8}\\ x=\dfrac{4+7}{8}\\ x=\dfrac{11}{8}\)

Answer 3

`a)15/6 + x = 19/3`

`=>x= 19/3 - 15/6`

`=> x= 23/6`

`b) x-7/8 = 1/2`

`=> x= 1/2 + 7/8`

`=>x= 11/8`

Answer 4

15/6 + x = 19/3
           x = 19/3 - 15/6 
          x = 23/6

x - 7/8 = 1/2 
     x   =  1/2 + 7/8
    x   = 11/8

Answer 5

\(a,\) \(\dfrac{\text{1}5}{6}+x=\dfrac{\text{1}9}{3}\) 

             \(x=\dfrac{\text{1}9}{3}-\dfrac{\text{1}5}{6}\) 

             \(x=\dfrac{23}{6}\) 

\(b,\) \(x-\dfrac{7}{8}=\dfrac{\text{1}}{2}\) 

            \(x=\dfrac{\text{1}}{2}+\dfrac{7}{8}\) 

            \(x=\dfrac{\text{1}\text{1}}{8}\)
