Which could be the first step in solving the equation represented by the model below? 3 x tiles and 4 negative 1 tiles = 2 x tiles and 5 positive 1 tiles Add 4 positive unit tiles to each side. Remove 4 unit tiles from each side. Add 6 positive unit tiles to each side. Remove 6 unit tiles from each side.

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.

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
