Che width of a room is 3 yards, and the length of the room is 6 times that nu he width of a room is 6 yards, and the length of the room is 3 less than tha he width of a room is 3 yards, and the length of the room is 6 more than t e width of a room is 6 yards, and the length of the room is 3 more than e width of a room is 6 yards, and the length of the room is 3 times that parison statement is BEST represented by the equation 6 x 8 = 48?

answer: -1

answer: it's d

step-by-step explanation:

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2
