expand (-9x+4y=6,9)(x+5y=-33)

expand

(- 9 x + 4 y = 6, 9) (x + 5 y = - 33)

- 9 xx - 9 \cdot 5 x y = 9 \cdot 33 x + 4 y = 6, 9 x + 4 y = 6, 9 \cdot 5 y = - 4 y = 6, 9 \cdot 33

Solution steps

(- 9 x + 4 y = 6, 9) (x + 5 y = - 33)

= (- 9 x + 4 \cdot 6 \cdot 9 =, y) (x + 5 = y - 33)

Distribute parentheses

(- 9 x) x + (- 9 x) \cdot 5 y = (- 9 x) (- 33) + 4 y = 6, 9 x + 4 y = 6, 9 \cdot 5 y = 4 y = 6, 9 (- 33)

Apply minus-plus rules

+ (- a) = - a, (- a) (- b) = ab

- 9 xx - 9 \cdot 5 x y = 9 \cdot 33 x + 4 y = 6, 9 x + 4 y = 6, 9 \cdot 5 y = - 4 y = 6, 9 \cdot 33

(x^{2} + Δ x^{2} - 2)^{3}
