Answer:

\tt b=40

<u>Step-by-step explanation:</u>

\tt 4 ( b + 5 )- 2b = 100

\bf Expand\; (Apply\; Distributions\; Law) :-

\tt 2b+20=100

\tt 2b+20-20=100-20\;\; (Subtract \;20\; from\; both \;sides)

\tt 2b=80  \tt (Simplify)

\tt \cfrac{2b}{2}=\cfrac{80}{2}\;\;( Divide\; both \;sides\: by\; 2)

\tt b=40
