Ayuda con esta ecuacion por favor

4/x + 7 = -1/x + 2

Answer 1

I'm assuming you want that solved. I will try to help you but I don't speak Spanish.

4/x+7=-1/x+2

I'm assuming that x+7 is all part of the denominator, and x+2 is all part of the other denominator...
Like this:
4/(x+7)=-1/(x+2)

4(x+2)=-1(x+7) (cross multiply)

4x+8=-x-7 (distribute)

5x+8=-7 (add 1x to both sides)

5x=-15 (subtract 8 from both sides)

x=-3 (divide both sides by 5)


I hope this helps. I don't speak Spanish, but I hope you speak English so that I can help you!

Best of luck!
