Explain how you can determine that the following system has one unique solution – without actually solving the system.

there are no short passages to look at

d. vertex

step-by-step explanation:

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

the answer is y = 11.54

hope this : )
