4x+4(2x-1)=20
4x + 4 x 2x - 4 x 1 =20
4x + 8x - 4 =20
12x - 4 =20
+4 +4=
12x/12 = 24/12
=2

4x+4(2x-1)=20
distrubute the 4 = 4*2x-1*4 = 8x-4
4x+8x-4=20
combine the x values
12x-4=20
add the 4 to the other side
12x=24
divide by 12
x=2

4x+4(2x-1)=20
4x+8x-4=20 by distributive prop
12x-4=20 combine like terms
12x-4+4=20+4 get 12x alone
12x=24
12x/12=24/12 divide both sides by 12
x=2
plug 2 for x to check if I made a mistake somewhere (but I didn't :)

4x + 4(2x - 1) = 20
Multiply out the brackets.
4x + 8x - 4 = 20
Add up like terms.
12x - 4 = 20
Add 4 to both sides.
12x = 24
Divide both sides by 12.
x = 2
