Question

3. Resolver las siguientes ecuaciones
racionales

a. 5/3x-1 = 4+2/3x

b. (2x+9) (4x -3) = 8x² - 12

c. 9X/3x-1 = 2+3/3x-1

d. x/x-2 - 4/x+1 = - 2/x+2


e. 2/x + 3/x² = 1


​

Answer 1

Respuesta:

5x/3 - 1 = 4 +2x/3

5x/3 - 2x/3 = 4+1

3x/3 = 5

x = 5

(9x/3x-1) = 2 + (3/3x-1)

(9x/3x-1) = 2(3/3x-1)/(3/3x-1) + (3/3x-1)

9x=2(3/3x-1)+3

9x=6x-2+3

9x=6x+1

3x=1

x=1/3
