Question

solve for x
(x-2)/(x+5) = (x+2)/(x+3)

Answer 1

cross multiply and post what you get

Answer 2

if I cross multiply then I get 6/10 or 2/5

Answer 3

but I am pretty sure you don't just cross multiply

Answer 4

not quite

Answer 5

actually you do cross multiply

Answer 6

exactly my point. I don't understand so I need help. I am sure you do, but there has to be more too it.

Answer 7

(x-2) (x+2)
----- = ---------
(x+5) (x+3)

Answer 8

Cross multiply.

Answer 9

Cross multiply is voodoo, but I suppose it helps some people remember

Answer 10

okay, well this is what we will do: (x-2)(x+3)=x^2+x-6
(x+2)(x+5)=x^2+7x+10

Answer 11

i did cross multiply and got the wrong answer

Answer 12

vjay, stop that.

Answer 13

now: x^2+x-6=x^2+7x+10

Answer 14

now subtract x^2 from both sides

Answer 15

(x-2) (x+3) = (x+2)(x+5)

x^2 +3x - 2x - 6 = x^2 + 5x + 2x + 10

Answer 16

subtract 10 from both sides

Answer 17

then subtract x from both sides

Answer 18

you should be left with : -16=6x

Answer 19

divide both sides by 6 and get: -16/6=x, which simplifies to -8/3 =x

Answer 20

satified?

Answer 21

Now shuffle,

x^2 +3x - 2x - 6 = x^2 + 5x + 2x + 10

x -7x = 10 + 6

-6x = 16

x = -16/6

Answer 22

Finally,

x = -8/3

Answer 23

thank you everyone.
