6y+7y+2+5x-7 11y+5x-5
OpenStudy (katrinakaif):
6y + 7y + 2 + 5x - 7 Collect like terms such as the "y" terms and constant terms like 2 and - 7 6y + 7y = 13y 2 - 7 = -5 5x cannot add with another term so final answer is 13y + 5x -5
OpenStudy (katrinakaif):
Wait...Eliza how did you get 11y? 6y + 7y = 13 y..?
