  1. cikgu,soalan pertama tu jawapannya agak pelik laaa … dah banyak kali saya cuba tapi masih dapat nilai a=-1 … tetapi jawapan yg di nyatakan a=-15..

    • Jawapannya memang a=-15. Begini penyelesaiannya :

      2m-5-m = m+8-(2m-5)
      m-5 = m+8-2m+5
      2m = 18
      m = 9

      d = 2(9)-5-9
      = 4

      T7 = 9
      a+(7-1)(4) = 9
      a +24 = 9
      a = -15

  2. salam ckg..sy tida faham no soalan 11,18,19,20,21..sy bingung ckg.berkali-kali sy buat..ttp jwp salah…
