here,  let the longer piece be y and shorter piece be x now, according to the question, x+y=19     .............................equation (1) y=4+2x    ...............................equation (2) from equation 1 x+y=19 x+4+2x=19          substituting the value of y from equation 2 3x=19-4 x=(19-4)/3 x=5 now  substituting value of x in equation (2) y=4+2(5) y=4+10 y=14 so , the longer piece is 14 foot and the shorter piece is 5 foot
