expand-4(x-3y=4)

Solution

expand

- 4 (x - 3 y = 4)

Solution

- 4 x + 12 y = 4

Solution steps

- 4 (x - 3 y = 4)

= - 4 (x - 3 \cdot 4 = y)

Apply the distributive law:

a (b - c) = ab - a c

a = - 4, b = x, c = 3 y = 4

- 4 x - (- 4) \cdot 3 y = 4

Apply minus-plus rules

- (- a) = a

- 4 x + 4 \cdot 3 y = 4

Expand

- 4 x + 4 \cdot 3 y : - 4 x + 12 y

- 4 x + 12 y = 4
