Question

5/3x X-2/3=1/3            5/3-X x 2/3 =1/3            X+7/8x 16/21=3/2

Answer 1

`5/3 xx x - 2/3 = 1/3`

`5/3 xx x = 1/3 + 2/3`

`5/3 xx x = 3/3`

`5/3 xx x = 1`

`x = 1 : 5/3`

`x = 1 xx 3/5`

`x = 3/5`

 

`5/3 - x xx 2/3 = 1/3`

`x xx 2/3 = 5/3 - 1/3`

`x xx 2/3 = 4/3`

`x = 4/3 : 2/3`

`x = 4/3 xx 3/2`

`x= 12/6 = 2`

 

`x + 7/8 xx 16/21 = 3/2`

`x + 2/3 = 3/2`

`x = 3/2 - 2/3`

`x= 5/6`

Answer 2

`5/3xx x-2/3=1/3`

`5/3xx x=1/3+2/3=1`

`x=1:5/3`

`x=1xx3/5=3/5`

`5/3-x xx2/3=1/3`

`x xx2/3=5/3-1/3=4/3`

`x=4/3:2/3`

`x=4/3xx3/2=2`

`x+7/8xx16/21=3/2`

`x+2/3=3/2`

`x=3/2-2/3`

`x=9/6-4/6=5/6`

Answer 3

5/3x X-2/3=1/3  

5/3 x X      = 1/3 + 2/3 = 3/3 = 1

         x       = 1 : 5/3 = 1x 3/5 = 3/5

5/3-X x 2/3 =1/3 

      X x 2/3 = 5/3 -1/3 = 4/3

      X          = 4/3 : 2/3 = 4/3 x 3/2 = 2

 

X+7/8x 16/21=3/2

X + 2/3          = 3/2

x                    = 3/2 - 2/3 = 9/6 - 4/6 = 5/6

Answer 4

 

5/3x X-2/3=1/3 

5/3 x X=1/3+2/3

5/3x X = 1

X = 1: 5/3

X=1 x 3/5

X=3/5

          5/3-X x 2/3 =1/3       

X x 2/3 = 5/3-1/3

X x 2/3=4/3

X = 4/3: 2/3

X= 4/3 x 3/2

X=2

    X+7/8x 16/21=3/2

 X + 2/3 =3/2

X = 3/2 - 2/3

X = 9/6 - 4/6

X = 5/6
