What is the solution of the equation? 7y-4=9y+13-4y

y= 17/2 but write or type it as 17

                                                  2

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
