Question

x - 3 2/3 = 1,2

12 1/7 - x = 22 1/2

15 1/3 - y = 23 1/2

8,4 + y = -3,9

9 1/8 + x = - 1,5

5 1/4 + x = 1

ps. jeżeli ktoś mółgby wytłumaczyć to proszę tak :

x =

x =

x =

itp : )

Answer 1

x - 3 2/3 = 1,2

x = 1,2 + 3 2/3

x = 1 2/10 + 3 2/3

x = 1 1/5 + 3 2/3

x = 1 3/15 + 3 10/15

x = 4 13/15

 

12 1/7 - x = 22 1/2

x = 12 1/7 - 22 1/2

x = 12 2/14 - 22 7/14

x = - (22 7/14 - 12 2/14)

x = - 10 5/14

 

15 1/3 - y = 23 1/2

y = 15 1/3 - 23 1/2

y = 15 2/6 - 23 3/6

y = -(23 3/6 - 15 2/6)

y =  - 8 1/6

 

8,4 + y = -3,9

y = -3,9 - 8,4

y = - 12,3

 

9 1/8 + x = - 1,5

x = -1,5 - 9 1/8

x = -1 1/2 - 9 1/8

x = -1 4/8 - 9 1/8

x = - 10 5/8

 

5 1/4 + x = 1

x = 1 - 5 1/4

x = - (5 1/4 - 1)

x = - 4 1/4
