Пошаговое объяснение:

(y-5)/6 = 4/3

3*(y-5) = 6*4

3y - 15 = 24

3y = 24+15

3y = 39

y = 39:3

y = 13

------------------

2/5 = 6/(x+3)

2*(x+3) = 6*5

2x + 6 = 30

2x = 30-6

2x = 24

x = 24:2

x = 12

--------------------

5) 5/6 = 15/(2x-3)

5*(2x-3) = 15*6

10x - 15 = 90

10x = 90+15

10x = 105

x = 105:10

x = 10,5

------------------------

6) 12 : 4x/5 = 20 : 1/4

4x/5 * 20 = 12 * 1/4

16x = 3

x = 3:16

x = 3/16
