Multiply both sides by \(5\).
\[a=5a-\frac{15}{2}\]
Subtract \(5a\) from both sides.
\[a-5a=-\frac{15}{2}\]
Simplify \(a-5a\) to \(-4a\).
\[-4a=-\frac{15}{2}\]
Divide both sides by \(-4\).
\[a=\frac{-\frac{15}{2}}{-4}\]
Two negatives make a positive.
\[a=\frac{\frac{15}{2}}{4}\]
Simplify \(\frac{\frac{15}{2}}{4}\) to \(\frac{15}{2\times 4}\).
\[a=\frac{15}{2\times 4}\]
Simplify \(2\times 4\) to \(8\).
\[a=\frac{15}{8}\]
Decimal Form: 1.875
a=15/8
