Arectangular room is 2 times as long as it is wide, and it's perimeter is 24 meters. find the dimensions of the room.
the length is meters and the width is meters

I hope this is right I am bad at math but I think I understand this.

The length is 16 meters and the width is 8 meters.

Step-by-step explanation: The total length is 16 meters so each of the longer sides is 8 meters. The total width is 8 meters so each of the shorter sides is 4 meters long. I hope this helps you out.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
