  • no 53
    x+2+x+4+x+6 = 45
    3x + 12 = 45
    3x = 45-12
    3x = 33
    x = 33/3
    x = 11
    terkecil = x+2 = 11+2 = 13
    terbesar = x+6 = 11+6 = 17
    Hasil kali = 13 x 17 = 221

    no 54
    x+1+x+3+x+5 = 60
    3x + 9 = 60
    3x = 60-9
    3x = 51
    x = 51/3
    x = 17
    x+5 = 17+5 = 22
    x+1 = 17+1 = 18
    hasil jumlah = 22+18 = 40
