The length of a rectangle is 3 feet less than twice the width. the area is 65 square feet. find the length and width

It's a lot to take in, isn't it? I started off by confirming the formula a=lb

a=lb

65 = (x*2) - 3*x

l = (x*2) - 3

b=x

a=65

Now I tried plugging in random values. Eventually I came up with this;

65 = (6.5*2) - 3*6.5

65 = 13-3*6.5

65 = 10*6.5

65=65

Length = 10feet

Width = 6.5feet
