The length of a rectangle 1.6 times longer with the sum of width and length being 130 feet

Let  be the length, and  be the width.
If the length is 1.6 times the width, then

If the sum of the length and with (in feet) is 130, then
Substituting in the equation above, the expression  for , we get
 -->  -->  --> 
Ten, substituting the value found for  in  we find
 --> 
The two equations we set up at the start form a system of linear equations:

The answers are 20,30,80,180,960,890,1230,4560. on the first row
