Answer:

The answer to your question is: x = 57/5 and y = 13/5

Step-by-step explanation:

Data

x = longer piece = 1 foot less than four times of the smaller piece

y = smaller piece

Equations

                 x - 1 = 4y           (1)

                 x + y = 14           (2)           Clear y from the first equation

                y = (x - 1) / 4                       solve by substitution in 2

                x + (x - 1) / 4 = 14

               4x + x - 1 = 56

               5x = 57

                  x = 57 / 5    feet

               y = (57/5 - 1 ) / 4

               y = ((57-5)/5)/4

               y = 52/2 = 26/10 = 13/5
