Question

If 33 is added to half of a number,the result is double the number. Find the number

Answer 1

let the number be 'x'
33+(x/2)=2x
33=2x-(x/2)
33=3x/2
x=33.2/3
x=22

Answer 2

Let the number be x.
Then, According to question,

half of x + 33 = two times x

$\frac{x}{2} + 33 = 2x$

$\frac{x}{2} - 2x = - 33$

$\frac{x - 4x}{2} = - 33$

$\frac{ - 3x}{2} = - 33$

$- 3x = - 33 \times 2$

$- 3x = - 66$

$- x = \frac{ - 66}{3}$

$- x = - 22$

$x = 22$

So that's your answer.

Hope it'll help. :-D
