<u>SOLUTION:
</u>
Given, Carlos is building a screen door. The height of the door is 1 foot more than twice its width.
And height of the screen door is 7 feet high.
Let the width of the screen door be x feet wide.
Now, according to given information,
Height is 1 foot more than the 2 times of width. Hence we can form a equation as,
7 = 1 + 2x
2x = 7 – 1
2x = 6
x =
= 3
Hence, the width of the screen is 3 feet.
