solve for x.
\\(\frac{21}{x} = -\frac{7}{3}\\)
answer attempt 1 out of 2

Explanation:

Step1: Cross - multiply the equation

To solve for \(x\) in the equation \(\frac{21}{x}=-\frac{7}{3}\), we cross - multiply. Cross - multiplying gives us \(21\times3=- 7\times x\).
\[21\times3=-7x\]
\[63 = - 7x\]

Step2: Solve for \(x\)

We divide both sides of the equation \(63=-7x\) by \(-7\) to isolate \(x\).
\[x=\frac{63}{-7}\]
\[x=-9\]

Answer:

\(x = - 9\)
