Bill = 4b + 2. Ron = 8b - 5.
Bill + Ron = (4b + 2) + (8b - 5). = 4b + 8b + 2 - 5. = 12b - 3.
That's the expression for the total number of blocks used by both Bill and Ron.

The total number of blocks used by Bill and Ron is given by the expression 12 b − 3 . This is obtained by adding their individual block counts, simplifying the resulting expression. Bill contributes 4 b + 2 and Ron contributes 8 b − 5 .
