x/5 - 1 = 9 add one to each side
x/5 = 10 then multiply each side by 5

\[\frac{ x }{ 5 } * \frac{ 5 }{ 1 } = 10 * 5\]

on the left side since we're multiply we can cross cancel the two 5's for one is the denominator and the other is the numerator. once we cross cancel they become 1 so
x/1 also equals x
