Katherinead sally had $288 altogether. katherine gave 1/3 of her share to shally and their father gave $68 to shally. they now have the same amount of money. how much money did shally have at first?

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^
