- 4 / 3 + X = 1 / 15 - 2 / 4 - X = 4 / 67 / 9?

- 4 / 3 + X = 1 / 15 - 2 / 4 - X = 4 / 6 7 / 9. X - 4 / 6 = X % - 2 / 4 = - 3 / 7.

A) - 4 / 3 + X = 1 / 15

3x - 4 / 3 = 1 / 15

3x - 4 = 3(1 / 15)

3x - 4 = 1 / 3

3(3x - 4) = 1

9x - 12 = 1

9x = 1 + 12

9x = 13

b)

x = 13 / 9 - 2 / 4 - X = 4 / 6

4x + 2 / 4 = 2 / 3

4x + 2 = 4(2 / 3)

4x + 2 = 8 / 3

3(4x + 2) = 8

12x + 6 = 8

12x = 8 - 6

12x = 2

x = 2 / 12

x = 1 / 6

c)

7 / 9.

X - 4 / 6 =

7x / 9 = + 4 / 6

7x = 9(4 / 6)

7x = 6

x = 6 / 7

d)

X % - 2 / 4 = - 3 / 7

4x - 2 / 4 = - 3 / 7

4x - 2 = 4( - 3 / 7)

4x - 2 = - 12 / 7

7(4x - 2) = 12

28x - 14 = 12

28x = 12 + 14

28x = 26

x = 26 / 28

x% = 13 / 14 ; )

Espero te sirva.
