Question

(1-a)2x+(2a+1)x+a+0.5=0

Answer 1

(1-a)2x+(2a+1)x+a+0.5=0

Answer 2

2x-2ax+2ax+x+a+0.5=0

Answer 3

3x+a+0.5=0

Answer 4

x=(-a-0.5)/3

Answer 5

k!

Answer 6

distribute then combine like terms to get the value of x

Answer 7

a good theory to apply on such questions which traile told:)

Answer 8

I did the same .I think u can understand now @marzhan

Answer 9

And do it:) good luck

Answer 10

I don't think that you will be able to get the VALUE of x @traile.
There is TWO variables ( "a" & "x") for only ONE equation.
You will only end up with a simplified equation


3x + a + 0.5 = 0
x= (-a - 0.5 0)/3

what do you say ?

Answer 11

@Railey yup, you have a point , but I think that is the only way to get the value of x :))
I guess the letter a will be treated as constant also
xD

Answer 12

@traile : Greek letters generally are used to represent constants. Normal letters (like "a") are used to represent variables. It can be misleading sometimes. Anyway, it's mathematics, so , have fun above all !!

Answer 13

xD right :))))

Answer 14

0pening brackets
2x-2xa+2xa+x+a+0.5=0
3x+a+0.5=0
3x+a=0.5
3x=0.5-a
x=0.5-a/3

Answer 15

You forgot the negative sign on "0.5" when you moved it to the other side
(2nd & 3rd line)
