A pipe is to be cut up such that the second piece is 3 inches shorter than the first and the third piece isfour inches more than the first. How long is cach piece if the pipe is 84 inches long?

x = shortest piece

x-3  = next piece

x +4 = last piece                summed they equal 84 inches

 

 

 

x      +     x-3      +      x+4    = 84

3x + 1 = 84

3x = 83

x = 83/3  inches           now you should be able to find the other two lengths....
