At the theater one section of seats has eight rows with 12 seats in each row in the center of each of the first three rows are four broken seats that cannot be used how many seats can be used in the section

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
