For rectangles, we know that there are two of each measure (length and height). If the length is four times the width, then this means l = 4w. Because there are two of each, it becomes 2 * (4w), which represents the two length measures. Now we also have two width measures, which is 2w. The phrase 'at most' hints at to perimeter being greater than or equal to something.
The answer is
You have to write two equation:
'substract 22 from a number'
and:
'the result is doubled, the answer is 6 more than the original number'
then you change 'Y' in 2nd equation for left side of 1st equation:
count it and you get:
This means that X=50
The original number is 50.
