Solve the following system of equations y=-2x-5 and 2x-4y=0

x=-2 y=-1

Step-by-step explanation:

all you have to do is substitute -2x-5 for y in the second equation

2x-4(-2x-5)=0

2x+8x+20=0

10x=-20

x=-2

y=-2(-2)-5

y=4-5

y=-1

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
