Question

Can someone please go into detail on how they simplified this expression? Thanks!

: 4a - (4a-3)=4a 1(4a 3) Identity property
4a -4a + 3 Distributive property
0 -3 Combine like terms.
3 simplify
I really don't get how they got plus 3
Thanks again!

Answer 1

Explanation:

4a - (4a-3)

= 4a -1(4a - 3)

= 4a - 4a + 3 <--- Distributing the -1 over the parenthes

= 3 <---- ( as 4a - 4a = 0)
