We need to solve the equation:
3(b-4)+5b=44
There is only one unknown in the equation. The unknown is b.
We must isolate the unknown b on one side of the equation.
According the law of multiplication we can write the following:
3b-3*4+5b=44
3b-12+5b=44
(3b+5b)-12=44
8b-12=44
We shift a number from one side of an equation
to the other by writing it on the other side with the inverse operation,so we obtain:
8b=44+12
8b=56
b=56/8
b=7
