simplify (6y-9y)/(9xy)

simplify

\frac{6 y - 9 y}{9 x y}

- \frac{1}{3 x}

Solution steps

\frac{6 y - 9 y}{9 x y}

Add similar elements:

6 y - 9 y = - 3 y

= \frac{- 3 y}{9 x y}

Cancel the common factor:

y

= \frac{- 3}{9 x}

Cancel the numbers:

\frac{- 3}{9} = \frac{1}{- 3}

= \frac{1}{- 3 x}

Apply the fraction rule:

\frac{a}{- b} = - \frac{a}{b}

= - \frac{1}{3 x}

- 3 x^{2} + 15 x + 108

25 x^{4} - 10 x^{2} y^{2} + y^{4} - 100

cos^{2} (a) - sin^{2} (a)

(2 t^{5} - t^{2})^{2}

\frac{63 x ^{15} y ^{9}}{7 x y ^{11}}
