expand (1.4)(2x-4y=0)

expand

(1.4) (2 x - 4 y = 0)

2.8 x - 5.6 y = 0

Solution steps

(1.4) (2 x - 4 y = 0)

= (1.4) (2 x - 4 \cdot 0 = y)

Apply the distributive law:

a (b - c) = ab - a c

a = (1.4), b = 2 x, c = 4 y = 0

(1.4) \cdot 2 x - (1.4) \cdot 4 y = 0

2 (1.4) x - 4 (1.4) y = 0

Expand

2 (1.4) x - 4 (1.4) y : 2.8 x - 5.6 y

2.8 x - 5.6 y = 0
