expand-3(-2x-4v=1)

expand

- 3 (- 2 x - 4 v = 1)

6 x + 12 v = 1

Solution steps

- 3 (- 2 x - 4 v = 1)

= - 3 (- 2 x - 4 \cdot 1 = v)

Apply the distributive law:

a (b - c) = ab - a c

a = - 3, b = - 2 x, c = 4 v = 1

- 3 (- 2 x) - (- 3) \cdot 4 v = 1

Apply minus-plus rules

- (- a) = a

3 \cdot 2 x + 3 \cdot 4 v = 1

Expand

3 \cdot 2 x + 3 \cdot 4 v : 6 x + 12 v

6 x + 12 v = 1
