Answer: x=2 and y=−6

Step-by-step explanation: 2x+y=−2, 5x+3y=−8

2x+y=−2

2x+y+−2x=−2+−2x

y=−2x−2

5x+3y=−8

5x+3(−2x−2)=−8

−x−6+6=−8+6

−x=−2

−x /−1 = −2 /−1

x=2

y=−2x−2

y=(−2)(2)−2

y=−6

x=2 and y=−6

In a rectangle the length is 6 more than twice the width, if the perimeter is 60 inches, what is the width of the rectangle

Vitek1552 [10]

Length(l)= 2w+6
width(w)= w

Perimeter(P)= 60 inches= 2w+2l (divide each side by 2 to simplify)
P=30 in= w+l

Plug in expression for "l" to be able to add like terms.
P=30=w+l
P=30=w+(2w+6)
P= 30= 3w+6
P= 24= 3w
w= 8 inches

Answer:
The width of the rectangle is 8 inches.
