Answer:
x + 6
Step-by-step explanation:
From the question given above, the following data were obtained:
Length of rectangle = 3x + 6
Width of rectangle = 4x – 1
Width of door =..?
A careful observation of the diagram shows that the door is located along the length of rectangular room.
In a rectangle, two sides are equal. Therefore,
x + door + x = 3x + 6
Making door subject of the above formula, we have:
x + door + x = 3x + 6
door + x + x = 3x + 6
door + 2x = 3x + 6
Subtract 2x from both side
door + 2x – 2x = 3x + 6 – 2x
door = 3x – 2x + 6
door = x + 6
Therefore, the width of the door is x + 6

this equation ( /2x-1/=5)can be solved if we solve the following equations:
2x-1=5
2x-1=-5
1)We solve the first equation:
2x-1=5
2x=5+1
2x=6
x=6/2
x=2
2) we solve the second equation.
2x-1=-5
2x=-5+1
2x=4
x=-4/2
x=-2
The solutions of this equation /2x-1/=5 will be: x=3 and x=-2
Answer: x=3 and x=-2
