Answer 2

Answer:

the number is 30

Step-by-step explanation:

let the number be 'x'

then the equation formed will be

2x= $\frac{1}{2}x$ + 45

2x- $\frac{1}{2}x$ = 45

$\frac{(2x*2)-x}{2}$ = 45

$\frac{4x-x}{2}$ = 45

$\frac{3x}{2}$ = 45

x = $\frac{45*2}{3}$

x = $\frac{90}{3}$

x = 30

hence, the number is 30
