2(b - c)
= 2*b - 2*c
= 2b - 2c

The equation is true.

this equation is true because you would multiply the 2 by both b and negative c to get 2b-2c

Distributive property

2(b-c)=2*b-2*c

It is, and it's called the distributive property.

Think about it 2*(7-5) = 2*2 = 4 = 14-10 = 2*7-2*5

It's true. Technically, it's an identity, not an equation
