Express 3 - [\(\frac{x - y}{y}\)] as a single fraction
\(\frac{3xy}{y}\)
\(\frac{x - 4y}{y}\)
\(\frac{4y - x}{y}\)
3 - \(\frac{x - y}{y}\)
ব্যাখ্যা
(\(\frac{x -y}{y}\)); \(\frac{3}{1} - \frac{x y}{y}\)
= \(\frac{3y - (x - y)}{y}\)
= \(\frac{3y - x + y}{y}\)
= \(\frac{4y - x}{y}\)
= \(\frac{3y - (x - y)}{y}\)
= \(\frac{3y - x + y}{y}\)
= \(\frac{4y - x}{y}\)
