Question

Can someone tell me if these are right
21. Solve 1/3x+9 - 2/x+3 = 2
x=1
x=-23/6
x=-5/2*******
x=-5
Solve 8/x + 15/x^2= -1
x=5,-3*****
x=-5,-3
x=-5,3
x=5,3

Answer 1

both are incorrect unfortunately

Answer 2

ohhh

Answer 3

can you show me how you knew that i dont want the answer i just need help of ehy i got em right

Answer 4

It might help to multiply everything by the LCD (x+3)(3x+9) to clear out the fractions


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


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


now solve that second equation for x

Answer 5

x+3-2(3x^3)= 2(x+3)(3x^3)

Answer 6

no,

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


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


x+3 - 6x - 18 = 2(3x^2 + 18x + 27)


x+3 - 6x - 18 = 6x^2 + 36x + 54


-5x - 15 = 6x^2 + 36x + 54


0 = 6x^2 + 36x + 54 + 5x + 15


0 = 6x^2 + 41x + 69


6x^2 + 41x + 69 = 0


I'll let you finish

Answer 7

23/6
