Answer 4

is it : 5 / (x + 2) = x / 3 ??

Answer 5

hello ?

Answer 6

yes

Answer 7

its : 5 / x + 2 = x / 3

Answer 8

I believe you have a proportion
5 / (x + 2) = x / 3
cross multiply
x(x + 2) = (3)(5)
x^2 + 2x = 15

are you understanding this so far ?

Answer 9

yes

Answer 10

wait but its not a proportion? It says equation

Answer 11

Solve\[x^2+2 x-15=0 \]for x.

Answer 12

exactly

Answer 13

wait :3

Answer 14

x = {-5, 3}

Answer 15

@robtobey @texaschic101

Answer 16

we will continue..
x^2 + 2x = 15
x^2 + 2x - 15 = 0
(x + 5)(x - 3) = 0

x + 5 = 0
x = -5

x - 3 = 0
x = 3

so your answers are : x = -5 and x = 3

Answer 17

So the final answer would be x = {-5, 3} ?

Answer 18

yep

Answer 19

oh ok what about '' 2/y + 1/3 = 4/y''

Answer 20

2y + 1/3 = 4y --- subtract 2y from both sides
1/3 = 4y - 2y
1/3 = 2y -- divide both sides by 2
(1/3) / 2 = y
1/3 * 1/2 = y
1/6 = y

any questions ?

Answer 21

yeah so what would the final answer be?

Answer 22

y = 1/6

Answer 23

tysm! (:

Answer 24

sure thing :)
