Please do this one- don't troll I will report :)

-3.7

Step-by-step explanation:

(-y+5.3)+(7.2y-9)=6.2y+n

-y+5.3+7.2y-9=6.2y+n

5.3-9-y+7.2y-6.2y=n

-y+7.2y-6.2y=0 so we will not write the y

n=-3.7

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
