Solution steps

9 x - 3 y + 5 + (- x) - y + 4 + (- 5) x + 4 y - 9

Apply rule:

a + (- b) = a - b

5 + (- x) = 5 - x

= 9 x - 3 y + 5 - x - y + 4 - 5 x + 4 y - 9

- 3 y - y + 4 y = 0

= 3 x + 5 + 4 - 9

Add the numbers:

5 + 4 - 9 = 0

= 3 x

\frac{3 ^{8}}{3 ^{4}}

\frac{3}{4} + \frac{( - 1 )}{2} - \frac{6}{5}

(x + a)^{4}

\frac{a + 2}{2 a + 4}

\frac{2 x ^{2} y}{x y - y}
