Respuesta :

Formula should be 3x + 5 = 1/2x

Soultion:
3x - 1/2x = -5 
2 1/2x = -5 or 5/2x = -5

mutiply 2 to simplify 
2(5/2x) = -5 (2)
5x = -10 

divide 5 to find the value of x 
5x/5 = -10/5
x = -2

Answer: B. -2

Step-by-step explanation:

The given statement : Five more than a number tripled is half the number.

Let the number be x.

Then according to the given statement ,we have the following equation :-

[tex]3x+5=\dfrac{1}{2}x[/tex]

Multiply 2 on both sides , we get

[tex]2(3x+5)=x\\\\\Rightarrow\ 6x+10=x\\\\\Rightarrow\ 6x-x=-10\\\\\Rightarrow\ 5x=-10\\\\\Rightarrow\ x=\dfrac{-10}{5}=-2[/tex]

Hence, the number is -2.
