Subtract \(1\) from both sides.
\[\frac{x}{3}=\frac{7}{15}-1\]
Simplify \(\frac{7}{15}-1\) to \(-\frac{8}{15}\).
\[\frac{x}{3}=-\frac{8}{15}\]
Multiply both sides by \(3\).
\[x=-\frac{8}{15}\times 3\]
Use this rule: \(\frac{a}{b} \times c=\frac{ac}{b}\).
\[x=-\frac{8\times 3}{15}\]
Simplify \(8\times 3\) to \(24\).
\[x=-\frac{24}{15}\]
Simplify \(\frac{24}{15}\) to \(\frac{8}{5}\).
\[x=-\frac{8}{5}\]
Decimal Form: -1.6
x=-8/5
