Answer:
Step-by-step 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
[tex]2x+3=\frac{x}{2}+30\\\\2x+3-3=\frac{x}{2}+30-3\\\\2x=\frac{x}{2}+27\\\\2x-\frac{x}{2}=27\\\\\frac{2x*2}{1*2}-\frac{x}{2}=27\\\\\frac{4x}{2}-\frac{x}{2}=27\\\\\frac{4x-x}{2}=27\\\\\frac{3x}{2}=27\\\\x=27*\frac{2}{3}\\\\x=9*2\\x=18\\[/tex]
