Question

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

Answer 1

A. -13/6
B. -11
C. -8/3
D. -11/3

Answer 2

start by multiplying both left n right hand side by (x+4)*(x+3) first:

[-2/(x+4)]*(x+4)*(x+3)=[4/(x+3)]*(x+4)*(x+3)

what will u get?

Answer 3

they cancel each other out, right?

Answer 4

@agent0smith

Answer 5

Yes, so how will the eqn look like after the canceling each other out?

Answer 6

0=0?

Answer 7

Nope...I will do the left hand side for u:

[-2/(x+4)]*(x+4)*(x+3)
=-2*(x+3)=-2x-6

That will be =[4/(x+3)]*(x+4)*(x+3)
So would you cancel n simplify that plz?

Answer 8

Unfortunately the equation editor still doesn't work. Makes this so much harder than it should be.

Answer 9

4/x+4?

Answer 10

because the x+3's cancel??

Answer 11

^^^ 4*(x+4)

Answer 12

ahh okay, so then what?

Answer 13

@agent0smith i know >=<

@HelennnnnnC
the left and right hand side are equal so:
-2x-6=4x+4
u should be able to solve x from here :)

Answer 14

@superdavesuper i was just correcting helen's mistake, not yours :)

Answer 15

would it be 6x=-10

Answer 16

so -10/6 = -5/3?

Answer 17

but thats not one of the answers

Answer 18

4*(x+4) = 4x+16, i think you missed that helen

-2x-6=4x+16

Answer 19

oh so it's 6x=-22

Answer 20

Ooops...me bad in my last post - plz fix MY mistakes as well @agent0smith :)

keep going @HelennnnnnC u are almost there!

Answer 21

so then it's -11/3?

Answer 22

that is correct! :)
