10 kilos. If you weigh half your weight plus 5 kilos, half your weight must be 5 kilos.
X/2 + 5 = X
5 = X - X/2
5 = 2X/2 - X/2
5 = X/2
X = 5 x 2
X = 10

bird = 1/2 bird + 5 Kilo
multiply every thing by 2
2 B = 1B + 10 K
minus 1 bird from both sides
1Bird = 10 Kilos

10 kilos. Half its weight plus 5 = its entire weight, so obviously the 5 is the other half.

10 kilos because half its weight is 5, so the other half is 5 too.

let the weight of the bird be x
x/2 + 5 = x
x-x/2 = 5
x/2 = 5
x = 5*2
x = 10

Let x be the weight of the bird.
Your equation looks like:
x = 0.5x + 5
x-0.5x = 5
0.5x = 5
x = 10
Your bird weighs 10 kilos

It weighs 1/2 it weight +5kg or
weight = 1/2weight +5kg
weight -1/2 weight =1/2weight-1/2weight +5kg
1/2weight =5kg
weight = 10kg

(x/2)+5=x; (x+10)/2=x; x+10=2*x; 2x-x=10; x=10

That question can't be answered with those paramaters.
bird = (bird/2) + 5kg???
Oh and it's "weigh", not "weight"

First of all, it is "weigh", not "weight". "Weight" is the noun.
Second: what on earth is this?!
