expand-7(5x+42y=-69)

expand

- 7 (5 x + 42 y = - 69)

- 35 x - 294 y = 483

Solution steps

- 7 (5 x + 42 y = - 69)

= - 7 (5 x + 42 = y - 69)

Distribute parentheses

(- 7) \cdot 5 x + (- 7) \cdot 42 y = (- 7) (- 69)

Apply minus-plus rules

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

- 7 \cdot 5 x - 7 \cdot 42 y = 7 \cdot 69

Simplify

- 7 \cdot 5 x - 7 \cdot 42 y = 7 \cdot 69 : - 35 x - 294 y = 483

- 35 x - 294 y = 483

tan^{2} (x) (cot^{2} (x) - cos^{2} (x))

\frac{1}{x \cdot ( x - 1 )}

(4 - \frac{x}{3})^{5}

10 (1 - i w) (5 + i w) (10 - i w) (50 - i w)

\frac{3 x - 12}{( x + 5 ) ( x - 10 )}
