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
, we get
Ten, substituting the value found for
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".
