Question

rozwiąż równanie: x - 2/3 = 3/5 x + 5/9 = 5/6

Answer 1

x - 2/3 = 3/5

x = 3/5 + 2/3

x = 9/15 + 10/15

x = 19/15

x = 1 i 4/15

 

x + 5/9 = 5/6

x = 5/6 - 5/9

x = 15/18 - 10/18

x = 5/18

Answer 2

x-2/3=3/5

x=3/5+2/3

x=9/15+10/15

x=19/15

x=1i4/15

 

x+5/9=5/6

x=5/6-5/9

x=15/18-10/18

x=5/18
