Ummmmm, yeah the = is a -.
5(x + 4)/(x2 + 6x + 8) - 8(x + 2)/(x2 + 6x + 8)
(5x + 20 - 8x - 16)/(x2 + 6x + 8
(-3x + 4)/(x2 + 6x + 8)

asked • 06/07/18Algebra question about equivalent equations.
which of the following is equivalent to 5/(x+2) = 8/(x+4)?
a) (-3x+4)/(x^2+8)
b) -5/(x+4)
c)(-3x+4)/(x^2+6x+8)
d)(-3x+36)/(x^2+6x+8)
(btw / means over because they're fractions)
I got x=4/3 in the original equation but I m not exactly sure how to approach this problem. Am I supposed to plug in 4/3 as X or i don't know can someone please explain on approaching this please because I have no clue. :)
