There are 3 spider webs. The 1st web is twice as large as the second web. The 3rd web is 3 inches larger than the 1st web. The combined width of the 3 webs is 1 foot 6 in. How long is each web?

Let x be the width of the 1st spider web. (x/2) is the width of the 2nd spider web. (x + 3) is the legnth of the 3rd spider web.
all widths add up to 18 inches.
