5/6 =1+t/10
1/z-1=6,5/8
2/x=3/x-1
4/x=1=5/x
3/5=2x-1/2-5x
4/x=1=5/x
3/5=2x-1/2-5x
2x=1/1-2x=2/3

Answer 1

5/6 =1+t/10
50=6+6t
6t= 44
t=7 i 1/3

1/z-1=6,5/8
8=6,5z-6,5
6,5z=14,5
z= 2 i 1/13

2/x=3/x-1
2x-2=3x
x=-2

4/x=1=5/x
?

3/5=2x-1/2-5x
6-15x=10x-5
-25x=-11
x= 11/25


2x=1/1-2x=2/3
?

Answer 2

3/5=2x-1/2-5x
3/5 * 10=2x-1/2*10-5x
1 1/3=10x-5-5x
-10x+5x=-5-1 1/3
-5x=-6 1/3

Answer 3

5/6 =1+t/10 /*60
5 * 60 / 6 = 1 + t * 60 / 10
5 * 10 = 1 + t * 6
50 = 1 + t * 6
6t = 50 - 6
6t = 44 /:6
t = 8 i 2/3


1/z-1=6,5/8 / * z-1
1 = 6.5 * z- 1 /8 /*8
8 = 6.5 * z -1
9 = 6.5 *z /:6,5
z = 9/6.5
z = 1 i 2.5/6.5
z = 1 i 5.13


2/x=3/x-1 / * x
2 = 3x / x-1
2x - 2 = 3x
-x = 2 /* -1
x = -2

4/x=1=5/x ??? 2 znaki = ???

3/5=2x-1/2-5x /*5
3 = 10x - 5 / 2-5x
3 = 10x - 5 / 2 - 5x / * 2-5x
6 - 15x = 10x - 5
-25x = -11 /: -25
x = 11/25


4/x=1=5/x ??? 2 znaki = ???

3/5=2x-1/2-5x / *10
3 * 10 / 5 = 2x - 10/2 - 5x
3*2 = 2x - 5 - 5x
6 = -3x - 5
11 = -3x /: -3
x = -11/3
x = 3 i 2/3

2x=1/1-2x=2/3 ??? 2 znaki = ???
