Question

lve: -1 over 2 x + 1 = −x + 8

Answer 1

-1/(2x+1) or
(-1/2x)+1?

Answer 2

7



14

18 these are the only possible awnser

Answer 3

and 1 over 2

Answer 4

No post the proper question! There's a difference use parenthesis!

Answer 5

its multiply choice... so i t has to be one of those.

Answer 6

1 =-x+8
----
2x+1

1=(2x+1)(-x+8)
1=-2x^2+16x-x+8
1=-2x^2+15x+8
1-8=-2x^2+15x
-7=-2x^2+15x
-2x^2+15x=-7
-2x^2+15x+7=0
please do check my signs

Answer 7

i still have no awnser...

Answer 8

-1/(2x+1) = -x+8
-1 = -x+8(2x+1)
-1 = -2x^2-x+16x+8
-1+8 = 2x^2+15x
7 = x(2x+15)
7/x = 2x+15
(7-15)/x = 2x
-8/x = 2x
-8 = 2x^2
x^2 = -8/2
x = root of -4
x = -2
but i am not sure about this

Answer 9

-1 over 2 x + 1 = −x + 8
No wait i think he meant:
(-1/2)x+1 = -x+8
(1/2)x+1 = 8
x+2= 16
x = 14

Answer 10

THANKYOU

Answer 11

so from now on, use parenthesis!
