The values of x and y are:

Exercise 2: x = 6, y = √20 / 18

Exercise 3: x = 1, y = 9 / 14

Exercise 4: x = 8, y = 12

Exercise 5: x = 9 / 5, y = 4

Answer 2:

6 * y = 14 * √20 / (4 * 12)

6 * y = 14 * √20 / 48

6 * y = √20 / 3

y = √20 / 18

Answer 3:

1 * 9 = y * 14

y = 1 * 9 / 14

y = 9 / 14

Answer 4:

x * 12 = 12 * 5 + 36

x * 12 = 96

x = 96 / 12

x = 8

Answer 5:

x * 4 = 36 / 5

x = 36 / (5 * 4)

x = 36 / 20

x = 9 / 5
