12b+ -8b + + b How would you simplify this problem? The answer in the back of uour book says: 41/2b I wouls simplify it as:5b What is the correct answer?
rewite the expression as follows:
(12b) + (-8b) + (+b)
this makes each term in the expression more obvious.
now, factor the b out of each term as follows:
b(12-8+1) = b(5) = 5b
