Answer:choice number 2) 10 in, 18.5 in 31.5 inStep-by-step explanation:we collect and evaluate the like terms.like terms means the ones that can be evaluated. like 2y and 7y are like terms. they either can be added or subtracted to get an answer . 7y-2y =5y. but you cant subtrac or add 7y with 5 because they are not like terms.2y +1 + 7y + 3y + 5 = 60(2y+7y+3y)+(1+5) = 6012y + 6 = 60The 6 crosses the equal sign to the other side because of like terms.And becomes a minus12y = 60 - 612y = 54y = 4.5so,2y +1= 2 x 4.5 + 1 =107y = 7 x 4.5 = 31.53y + 5= 3 x 4.5 + 5 =18.5Answer is 10 in, 18.5 in, 31.5 inIf you need any clarification or more explanation pls do mention at the comment section so that i can help more thxHope this helps and if it does pls mark as branliest answer thx
