Question

Solve the equation. Check the solution. -2/x+4 = 4/x+3

Answer 1

\[\frac{-2}{x+4}=\frac{4}{x+3}\iff 4(x+4)=-2(x+3)\] and go from there

Answer 2

Satellite did you the courtesy of "cross-multiplying" that equation of fractions.

Answer 3

I'm completely lost still >.<

Answer 4

\[\frac{a}{b}=\frac{c}{d}\iff ad=bc\]

Answer 5

Ohh

Answer 6

solve the equation i wrote on the right hand side for \(x\)

Answer 7

So it would be

4x +16 = -2x - 6
and then I would add 6 to both sides
so
4x + 22 = -2x
and then take 4x away from both sides

22 = -6x
22/-6

simplify

11/-3?

Answer 8

Now, Dani: Why not check your result by substituting it back into the original equation? If the original eq'n is true when x=-11/3, then your solution is indeed a solution.
