Input: 3ax/5 - 4c = ax/5
Intepretation: \(\frac{3ax}{5}-4c=\frac{ax}{5}\)
Multiply by \(5\) on both sides:
\(3ax-20c=ax\)
Move the \(x\) term to the left, numeric ones to the right:
\(3ax-ax=20c\)
Simplify:
\(2ax=20c\)
Divide by \(2\) on both sides:
\(ax=10c\)
Finally, divide \(a\) on both sides:
\(x=\frac{10c}{a}\)
Done.
