Answer:

Step-by-step explanation:

Hello, please consider the following.

For any x real number different from 0, we can write.

$\dfrac{2y + x}{x} = 2y\\\\2y+x=2xy\\\\2xy-x=(2y-1)x=2y\\\\x=\dfrac{2y}{2y-1}$

And this is defined for 2y-1 different from 0, meaning y different from 1/2

Thank you.

The sales tax on a one-half-carat diamond ring is $76. Find the purchase price of the ring (before tax) of the sales tax rate is

NISA [10]

So.. hmmm if we take "x" to be the 100% sale price before tax, $76 is really 9.5% of that

thus $\bf \begin{array}{ccllll}
amount&\%\\
\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\
76&9.5\\
x&100
\end{array}\implies \cfrac{76}{x}=\cfrac{9.5}{100}$

solve for "x"
