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
