Answer 2

idk man

Answer 3

see
16 = 4x - 4
on adding 4 on both sides
16 + 4 = 4x - 4 + 4
20 = 4x

Answer 4

ok so the equation is
16=4x-4 then, you need to add 4 to both sides so the x could be by itself
so it would be.. 20=4x
after you get 20 = 4x, you divide 4 on both sides since you are trying to get x to be standing by itself. After you divide 4 on both sides you get
5=x OR x=5
So x=5 and 5 is the correct answer :D
