Question

(x+2) / (x-4) = (3x+1)/(x+2) How do I find x?

Answer 1

first u do cross multiplication

Answer 2

(x+2)(x+2)=(x-4)(3x+1)

Answer 3

\[x^2+4x+4=3x^2-11x-4\]

Answer 4

u know how to do the rest right?

Answer 5

Thanks ! Yes I do

Answer 6

:D:D

Answer 7

\[x=-(1/2), x=8\]

Answer 8

(x+2) / (x-4) = (3x+1)/(x+2)
find cross products
(x+2)(x+2)=(x-4)(3x+1)
\[x ^{2}+4x+4=3x ^{2}-11x-4\]\[2x ^{2}-15x-8=0\]\[(2x+1)(x-8)=0\]\[2x+1=0, x-8=0\]\[x=-1/2, x=8\]
