expand 9(-7x+9y=-25)

expand

9 (- 7 x + 9 y = - 25)

- 63 x + 81 y = - 225

Solution steps

9 (- 7 x + 9 y = - 25)

= 9 (- 7 x + 9 = y - 25)

Distribute parentheses

9 (- 7 x) + 9 \cdot 9 y = 9 (- 25)

Apply minus-plus rules

+ (- a) = - a

- 9 \cdot 7 x + 9 \cdot 9 y = - 9 \cdot 25

Simplify

- 9 \cdot 7 x + 9 \cdot 9 y = - 9 \cdot 25 : - 63 x + 81 y = - 225

- 63 x + 81 y = - 225

(- 2 - 2 i)^{7}

\frac{- 3 s + 1}{8 ( s ^{2} + s + 4 )}

(x - 1 - 5) (x - 1 + 5)

(7 - 2 i)^{5}

(- 3 + \frac{3 i}{n})^{2}
