x:16i 1/4=8 20i 1/2 :x=1i1/2 7i1/3+x=12i3/5 x-3i2/7=1i1/3 prosze o rozpisanie

Answer 1

x : 16i 1/4 = 8

x = 8 * 16i1/4

x = 8 * 65/4

x = 2 * 65/1

x = 130 

 

 

20i1/2 :x = 1 i1/2

x = 20i1/2 : 1 i1/2

x = 41/2 : 3/2

x = 41/2 * 2/3

x = 41/1 * 1/3

x = 41/3

x = 13 i 2/3

 

 

7 i1/3 + x = 12i 3/5

x = 12 i3/5 - 7 i 1/3

x = 12 i 9/15 - 7 i 5/15

x = 5 i 4/15

 

x - 3 i 2/7 = 1 i 1/3

x = 1 i1/3 + 3 i 2/7

x = 1 i 7/21 +3 i 6/21

x = 4 i 13/21
