The perimeter of a picture frame is 68 inches. The difference between the length of the frame and three times its width is 2. The system of equations

Respuesta :

Answer:

The width of the frame is 8 inches and the length of the frame is 26 inches

Step-by-step explanation:

The complete question in the attached figure

Let

L ----> the length of the frame in inches

W ---> the width of the frame in inches

we have

[tex]2L+2W=68[/tex] ----> equation A

[tex]2L-6W=4[/tex] ----> equation B

Solve the system by elimination

Subtract equation B from equation A

[tex]2L+2W=68\\-(2L-6W)=-4\\---------\\2W+6W=68-4\\8W=64\\W=8\ in[/tex]

Find the value of L

substitute the value of W in any equation

[tex]2L+2(8)=68[/tex]

[tex]2L+16=68[/tex]

[tex]2L=68-16[/tex]

[tex]2L=52[/tex]

[tex]L=26\ in[/tex]

therefore

The width of the frame is 8 inches and the length of the frame is 26 inches
