Hey there!

It's the distributive property, which states that:

a(b + c) = ab + ac

And that's exactly what was used here. 2(2x - 3) was simplified to 2(2x) - 2(3) 
= 4x - 3

Hope this helps!
This property is called the distributive property, as the 2 is distributed to both 2x and -3

hope this helps
