How do I solve -3y - 5 = 10

y=-5

Step-by-step explanation:

first add 5 to both sides.       -3y=15

then divide both sides by -3.      y=-5

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
