A 210 ft. long rope is cut into 3 pieces. The first piece of rope is 3 times as long as
the second piece of rope. The third piece of rope is 2 times as long as the second
piece of rope. What is the length of the longest piece of rope?

second piece  x
first piece  3x
third piece  2x
solve:
x + 3x + 2x = 210 
x+3x+2x=210
2x_3x=210
