HI!!

Answer 2

i made two typos \[ −3.5(2 − 3n) − 2.5n\] multiply out get \[-3.5\times 2-3.5\times 3-2.5n\]

Answer 3

dang another typo \[-3.5\times 2-3.5\times 3n-2.5n\]

Answer 4

now you got \[-7+10.5n-2.5n\] last step is to combine like terms

Answer 5

do \(10.5-2.5\) then put the \(n\) next to it
