    college algebra

    A carpenter used 30ft of molding three pieces to trim a garage door.. if the long piece was 2ft longer than twice the length of each shorter piece, then how long was each piece?
    I am thinking the equation is 30= 2( p+p)+2 +p +p

    p = length of short pieces

    the long piece was 2ft longer than twice the length of each shorter piece

    long piece = 2+2p

    30 = 2p + (2p+2)
