Answer 2

Explanation:

Let the number be x

Two times a number: 2x

Two times a number plus three : 2x +3

one half of the number plus thirty: (x/2)+30

`2x+3=(x)/(2)+30\\\\2x+3-3=(x)/(2)+30-3\\\\2x=(x)/(2)+27\\\\2x-(x)/(2)=27\\\\(2x*2)/(1*2)-(x)/(2)=27\\\\(4x)/(2)-(x)/(2)=27\\\\(4x-x)/(2)=27\\\\(3x)/(2)=27\\\\x=27*(2)/(3)\\\\x=9*2\\x=18\\`
