length of original pieces : x and 3x
length of pieces after 4 ft cut off from each : x-4 and 3x-4
x-4 + 3x-4 = 4
4x = 12
x = 3
original pieces were 3 ft and 9 ft.
check:
new pieces: -1 and 5 , whose sum is 4 ?????
Even though the solution makes sense arithmetically, in reality this is a dumb question.
how can you cut off 4 ft from a ribbon only 3 ft long?
