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

Question

anonymous · Answer

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

mathmale · Answer

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

I'm completely lost still >.<

anonymous · Answer

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

anonymous · Answer

Ohh

anonymous · Answer

solve the equation i wrote on the right hand side for $x$

anonymous · Answer

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?

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.
