                       Write a linear equation in one variable for each of the   peserta yang menerima hadiah, cari nilai x.
                       following.                                               If the number of participants who do not receive
                       (i)  Satu nombor ditolak dengan 6, bakinya ialah         prizes is one-third the number of participants who
                           3.                                                   receive prizes, find the value of x.
                           Subtract 6 from a number, its remainder is 3.    (ii)  Seterusnya, hitung  bilangan peserta  yang
                       (ii)  Dua kali suatu nombor ditambah dengan 8,           menerima hadiah.
