2(4b+20)=56
*First, you distribute the 2 and get rid of the parenthasees.
2x4b=8b 2x20=40
6b+40=56
**Next, subtract 40 from both sides.
8b+40-40(cancels out)=56-40=16
So you get 8b=16
***Now divide by 8 on both sides
16 divided by 8
and get the b=2

2(4b+20)=56
Distribute.
8b+40=56
Subtract 40 from both sides.
8b+40-40=56-40
8b=16
Divide each side by 8.
8b/8=16/8
So then:
b=2
Get it now? ^-^
