expand 2(-3x-6y=12)

expand

2 (- 3 x - 6 y = 12)

- 6 x - 12 y = 12

Solution steps

2 (- 3 x - 6 y = 12)

= 2 (- 3 x - 6 \cdot 12 = y)

Apply the distributive law:

a (b - c) = ab - a c

a = 2, b = - 3 x, c = 6 y = 12

2 (- 3 x) - 2 \cdot 6 y = 12

Apply minus-plus rules

+ (- a) = - a

- 2 \cdot 3 x - 2 \cdot 6 y = 12

Expand

- 2 \cdot 3 x - 2 \cdot 6 y : - 6 x - 12 y

- 6 x - 12 y = 12

P (- 2, 7, 3) y Q (1, 2, - 2)

(2 x - 3) (3 ln (x))

(6 x y + 10 x) d x + (3 x^{2} + 8 y) d y

(y - x \frac{d y}{d x})^{2}

\frac{8 x + 16}{( x - 4 ) ( x + 4 )}
