<u>Multiply 3 and 5x = 15x:-</u>
<u>Combine like terms:</u>
<u>Expand: 3x-(2x-1)= x+1</u>
<u>Subtract 1 from both sides:</u>
<u>Add 9x to both sides:</u>
<u>Divide both sides by 10:</u>

Answer:
3.75 feet
Step-by-step explanation:
The length of the frame is 3 times the width.
Let the width be x.
The length will be 3x.
Kyle uses 10 feet of wood to make the frame. This means that the perimeter is 10 feet.
The perimeter of a rectangle is:
P = 2(L + W)
=> 10 = 2(3x + x)
=> 10/2 = 4x
5 = 4x
=> x = 5/4 = 1.25 feet
The width is 1.25 feet. The length is therefore:
1.25 * 3 = 3.75 feet
