Equação Fracionaria

1 sobre 3x - 3 + 1 sobre 2x+2= 4 sobre x(ao quadrado) -1

Answer 1

Ola Camila

1/(3x - 3) + 1/(2x + 2) = 4/(x² - 1)

1/3*(x - 1) + 1/2*(x + 1) = 4/(x² - 1)

mmc = 6

2/(x - 1) + 3/(x + 1) = 24/(x² - 1)

2*(x + 1) + 3*(x - 1) = 24

2x + 2 + 3x - 3 = 24

5x = 24 + 3 - 2 = 25

x = 25/5 = 5

.

Answer 2

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

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

4x/12-36/12+6x/12+24/12=3x/12

4x-36+6x+24=3x/12

4x+6x-3x=36-24

10x-3x=12

7x=12

x=12/7
