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:

and what we did above is solve it "by substitution".
